00:21:41E Bar Dekho,
00:21:43Yes.
00:21:45Ok.
00:21:47Now we will
00:21:49go to logic gate.
00:21:51There are four types of logic gates.
00:21:53We have to learn three at HSE level.
00:21:55Moulik logic gate,
00:21:57Moulik logic gate,
00:21:59Moulik logic gate,
00:22:01Sharbozani logic gate,
00:22:03Exclusive logic gate.
00:22:05What is logic gate?
00:22:07Logic gate is an electronic circuit
00:22:09where one or more input
00:22:11can be one or more
00:22:13but
00:22:15one or more input
00:22:17will give only one output.
00:22:19And that
00:22:21depends on logic.
00:22:23The logic gate
00:22:25you follow,
00:22:27you will learn it in your language.
00:22:29It is like this.
00:22:31Logic gate is
00:22:33an electronic circuit
00:22:35where
00:22:37one or more input
00:22:39can be one or more
00:22:41but
00:22:43one or more output
00:22:45depends on logic.
00:22:47The main point is
00:22:49one or more input
00:22:51can be one or more
00:22:53but
00:22:55one or more output
00:22:57can be one or more
00:22:59but
00:23:01one or more output
00:23:03depends on logic.
00:23:05If you ask it to joke,
00:23:07it will joke and give output.
00:23:09If you ask it to goon,
00:23:11it will goon and give output.
00:23:13It depends on logic.
00:23:15The logic in which you ask it to work,
00:23:17it depends on logic and
00:23:19it will give output.
00:23:21Output will always be one.
00:23:23Now see, Moulik logic gate.
00:23:25Moulik logic gate
00:23:27is of three types.
00:23:29First we will learn Moulik logic gate,
00:23:31then Sharbozani and then Exclusive.
00:23:33These are very important.
00:23:35See,
00:23:37whatever we will learn in today's class,
00:23:39these are super duper important.
00:23:41See,
00:23:43listen carefully,
00:23:45they will be tested.
00:23:47Moulik logic gate.
00:23:49See, Moulik logic gate
00:23:51is of three types.
00:23:53We learned these in the last class.
00:23:55Do you remember?
00:23:57OR gate works for Jog,
00:23:59AND gate works for Goon,
00:24:01NOT gate works for Purakh.
00:24:03These three gates,
00:24:05everyone remembers.
00:24:07Whatever we will learn in today's class,
00:24:09will be tested.
00:24:11So listen, what is there in logic gate?
00:24:13In logic gate,
00:24:15there can be one input,
00:24:17but there will be only one output.
00:24:19And that output depends on
00:24:21what you ask it to do,
00:24:23or what logic it depends on.
00:24:25If you ask it to Jog,
00:24:27it will Jog. If you ask it to Goon,
00:24:29it will Goon. If you ask it to Purakh,
00:24:31it will Purakh.
00:24:33Now see, OR gate.
00:24:35Come to the beginning.
00:24:37What is OR gate? Write.
00:24:39OR gate.
00:24:41These are three Moulik gates.
00:24:43OR gate, AND gate,
00:24:45and NOT gate.
00:24:47OR gate works for Jog.
00:24:49What does OR gate do?
00:24:51It works for Jog. Now tell me,
00:24:53how many minimum inputs will it take to work for Jog?
00:24:55Will it be Jog with one input?
00:24:57To do Jog,
00:24:59minimum input will be two.
00:25:01It can be more than that.
00:25:03Two or more than that.
00:25:05No problem.
00:25:07Now see,
00:25:09OR gate has two inputs.
00:25:11Minimum two.
00:25:13It can be more than that.
00:25:15OR gate's input
00:25:17can be
00:25:19minimum two or more than that.
00:25:21But minimum two will be required.
00:25:23So OR gate's sign is like this.
00:25:25Make it bigger.
00:25:27Then make it like this.
00:25:29This is OR gate's sign.
00:25:31And output.
00:25:33We have shown the output with Y.
00:25:35Output will be Jog.
00:25:37Because this is a logic gate.
00:25:39Output will be one.
00:25:41And output depends on
00:25:43what logic OR gate does for Jog.
00:25:45Then it will be Jog.
00:25:47This is OR gate's sign.
00:25:49Write.
00:25:51This is OR gate's
00:25:53sign.
00:25:55Sign.
00:25:57This is
00:25:59OR gate's sign.
00:26:01See,
00:26:03you have two inputs.
00:26:05If you put these two
00:26:07in OR gate's input,
00:26:09OR gate will Jog these two inputs.
00:26:11If you put three,
00:26:13A, B, C,
00:26:15A+, B+, C,
00:26:17A+, B+, C, D.
00:26:19Do you understand?
00:26:21Write.
00:26:23You have two inputs.
00:26:25A and B.
00:26:27If you put these two in OR gate's input,
00:26:29what will be the output?
00:26:31A Jog B.
00:26:33But in ICT,
00:26:35in ICT,
00:26:37A plus B.
00:26:39In ICT, it is called A OR B.
00:26:41Do you understand?
00:26:43When I said Jog,
00:26:45there was no problem.
00:26:47That's why I didn't cut the number.
00:26:49In ICT,
00:26:51if sir asks you
00:26:53A plus B,
00:26:55if he asks you to read this,
00:26:57you won't say A Jog B.
00:26:59You will say A OR B.
00:27:01Because,
00:27:03in Boolean Algebra,
00:27:05Jog means OR.
00:27:07Do you understand?
00:27:09This is for reading.
00:27:11It doesn't matter
00:27:13if you say A plus B or A OR B.
00:27:15Now, let's see
00:27:17how is OR gate's
00:27:19positive derivative.
00:27:21Let's see.
00:27:25Positive derivative.
00:27:29Input.
00:27:31Two.
00:27:33How many are there? Two.
00:27:35A and B.
00:27:37Output.
00:27:39What will be A plus B?
00:27:41Let's see.
00:27:45I can box it.
00:27:47Let's see.
00:27:55Yes, it is correct.
00:27:57Now,
00:27:59these two inputs, A and B,
00:28:01what can be the value of each of them?
00:28:03It can be 0 or 1.
00:28:05It can't be outside of A.
00:28:07Right?
00:28:09It can't be outside of A.
00:28:11Let's see serialize binary.
00:28:130 0 0 1
00:28:151 0 1 1
00:28:17Now,
00:28:190 and 0 is 0.
00:28:210 and 1 is 1.
00:28:231 and 0 is 1.
00:28:251 and 1 is 1.
00:28:27In Boolean Algebra, 1 and 1 is 1.
00:28:29I have shown it in the last class.
00:28:31This is called positive derivative.
00:28:35What is its name?
00:28:37Check the input and output like this.
00:28:41This is called
00:28:43positive derivative.
00:28:47Now, we are studying OR gate.
00:28:49In OR gate, we have seen
00:28:51how many inputs can be there.
00:28:53Minimum two inputs can be there.
00:28:55It can be more.
00:28:57Right?
00:28:59This is the sign of OR gate.
00:29:01We will see this sign somewhere.
00:29:03It is like this.
00:29:05This is the sign of OR gate.
00:29:07This is positive derivative.
00:29:09In the last class, I told you
00:29:11that
00:29:13think about two switches.
00:29:15If a light
00:29:17goes through two switches
00:29:19and OR operation is being done,
00:29:21when two switches are OFF,
00:29:23when two switches are OFF,
00:29:25then output is OFF.
00:29:27Light will be OFF.
00:29:29If
00:29:31one switch is ON,
00:29:33if one switch is ON,
00:29:35if two switches are ON,
00:29:37if one switch is ON,
00:29:39then output will be true.
00:29:41It means light will be ON.
00:29:43Do you remember?
00:29:45In 1910, there was science.
00:29:47I will show you the circuit.
00:29:49How does the circuit work?
00:29:51If you were not in science,
00:29:53if you were not in science background,
00:29:55if you did not learn this circuit,
00:29:57there is no problem.
00:29:59Because this circuit will not be tested.
00:30:01I will show you the circuit.
00:30:03I will show you the circuit.
00:30:05Those of you who were in science,
00:30:07you learned this circuit.
00:30:09I will show you the circuit.
00:30:11I will show you the circuit.
00:30:13Hold this.
00:30:15This is a positive circuit.
00:30:17This is a negative battery.
00:30:19There is a LED here.
00:30:23Hold the switch here.
00:30:25Make the LED smaller.
00:30:27Hold two parallel switches.
00:30:41There is a bulb here.
00:30:47This is a light.
00:30:51See.
00:30:53There are two switches here.
00:30:55This is a bulb.
00:30:57This is a battery.
00:30:59When you are going with the battery,
00:31:01which direction will the current go?
00:31:03It will go in the positive direction.
00:31:05It will go out in the negative direction.
00:31:07There are two switches here.
00:31:09With these two switches,
00:31:11you are controlling one light.
00:31:13Now tell me.
00:31:15When both the switches are OFF,
00:31:17OFF means open.
00:31:19Switch means open.
00:31:21When the light is OFF,
00:31:23switch is OFF.
00:31:25The circuit is not complete.
00:31:27The circuit is not filled up.
00:31:29There is a gap in the middle.
00:31:31This is OFF.
00:31:33Both the switches are OFF.
00:31:35If both the switches are OFF,
00:31:37will the current go in this direction
00:31:39and pass through this direction?
00:31:41Both the switches are OFF.
00:31:43Both the switches are OFF.
00:31:45The current cannot pass through this direction.
00:31:47Then the bulb will not light.
00:31:49The bulb will not light.
00:31:51This time,
00:31:53suppose one switch is OFF.
00:31:55This is OFF and this is 0.
00:31:57This is 0 and this is 1.
00:31:59This is ON.
00:32:01This is OFF and this is ON.
00:32:03Suppose you switch this switch ON.
00:32:05With this switch tip,
00:32:07the gap will be filled up.
00:32:09The circuit will be filled up.
00:32:11When the current passes through this direction,
00:32:13it will see that
00:32:15one switch is OFF
00:32:17and one is ON.
00:32:19The circuit will be filled up.
00:32:21The current will pass through this direction
00:32:23and pass through this direction.
00:32:25Then the bulb will light.
00:32:27Do you understand?
00:32:29One switch is OFF and one is ON.
00:32:31Then the bulb will light.
00:32:33If this switch is ON,
00:32:35this circuit is filled up and this is OFF.
00:32:37In that case, the bulb will light.
00:32:39If both the switches are ON,
00:32:41this switch is ON
00:32:43and this is ON.
00:32:45Then the current will pass through both the switches
00:32:47and the bulb will light.
00:32:49Do you understand?
00:32:51This circuit is called
00:32:53logic circuit.
00:32:55But logic circuit will work
00:32:57even without an exam.
00:33:01The main thing is
00:33:03connection.
00:33:05At first,
00:33:07I was told to explain OR gate.
00:33:09In the beginning, you will give a connection.
00:33:11What will you say with the OR gate?
00:33:13The value of the logic gate
00:33:15will be
00:33:19the number of inputs
00:33:21that will be
00:33:22connected to the output.
00:33:24The logic gate
00:33:26will work as a connector.
00:33:28The value of the logic gate
00:33:30will be OR gate.
00:33:34Input will be
00:34:06Now, let's
00:34:26show you
00:47:15how we can implement a logic function using a Maulik gate and how we can implement a Maulik
00:47:23gate using a Sharbhajanin gate.
00:47:25Sharbhajanin gate and Nor gate are called Sharbhajanin gates.
00:47:28Sharbhajanin gate and Nor gate are called Sharbhajanin gates.
00:47:31Sharbhajanin gate and Nor gate are called Sharbhajanin gates.
00:47:34Sharbhajanin gate and Nor gate are called Sharbhajanin gates.
00:47:37Sharbhajanin gate and Nor gate are called Sharbhajanin gates.

01:10:37NOT
01:10:40So, this time I will use this AND gate.
01:10:45What will I use this AND gate for?
01:10:49Sorry, why did I joke?
01:10:56I will use this AND gate for NAND gate.
01:10:59Okay, tell me, how many inputs are there here?
01:11:02Two.
01:11:03And two variables, one A and one B.
01:11:05So, it is not difficult for me to take two variables here.
01:11:08A and B.
01:11:09Two variables.
01:11:10What gate will I take? NAND gate.
01:11:12NAND gate is the gate in front of the GUN.
01:11:15Now, look here.
01:11:16I have taken two inputs, one A and one B.
01:11:18So, what will be the output here?
01:11:19I will write the output below, not above.
01:11:21Look, what will happen?
01:11:22It will be GUN from this distance.
01:11:25It will be GUN and then PUROK.
01:11:26Do you understand?
01:11:27Look,
01:11:29we will activate the output of the AND gate
01:11:34through what?
01:11:35Through the NAND gate.
01:11:36First,
01:11:37we saw that there are two inputs and two variables.
01:11:40We took two variables.
01:11:41Then,
01:11:42this is the symbol of the NAND gate.
01:11:45We activated GUN from both.
01:11:47It will be GUN and then PUROK.
01:11:48Now, tell me,
01:11:49what actually happened?
01:11:50Hey, tell me, what actually happened?
01:11:53The output of the AND gate is A, B.
01:11:56And the output of the NAND gate is A, B bar.
01:11:58Are they the same?
01:11:59No, they are not.
01:12:00So, what can we do if they are not the same?
01:12:02We have to put this in another NAND gate.
01:12:04Wait.
01:12:05Because we will actually activate the AND gate through the NAND gate.
01:12:08So, we have to use only the NAND gate here.
01:12:11We cannot use any other gate.
01:12:12Now, if I put another NAND gate in front of it,
01:12:14tell me,
01:12:16tell me,
01:12:17should I put one input in the NAND gate?
01:12:22Here, I put another NAND gate.
01:12:24How many inputs are there?
01:12:25One.
01:12:26Here, the input is one.
01:12:28Should I put one?
01:12:29No.
01:12:30Then, what should I do?
01:12:31I will take this twice.
01:12:33There is no problem if I take it twice.
01:12:34Look at this.
01:12:36Do you understand?
01:12:37Listen,
01:12:38there are two variables here, A and B.
01:12:40We have already taken A and B.
01:12:43So, we cannot make a new variable here.
01:12:46Again,
01:12:47because the output is not the same,
01:12:50I have to take the NAND gate again.
01:12:53So, what does NAND gate mean?
01:12:54Minimum two inputs are required.
01:12:56So, what did I do for two inputs?
01:12:57I put the same input again.
01:12:59That means,
01:13:00this line,
01:13:01this line,
01:13:02look,
01:13:03this is also an A B bar,
01:13:04and this is also an A B bar.
01:13:05Wait, I will write it for you.
01:13:06This is also an A B bar.
01:13:09Now, two inputs,
01:13:10the same thing.
01:13:11This is another NAND gate.
01:13:13What will NAND gate do?
01:13:15Look,
01:13:16NAND gate will gather these two inputs first.
01:13:17Wait, I will put the output.
01:13:19These two inputs,
01:13:20A B bar
01:13:22and A B bar,
01:13:24it will gather these two inputs first.
01:13:26Look,
01:13:27A B bar,
01:13:28A B bar.
01:13:29NAND gate will gather these two inputs first
01:13:31and then it will complete.
01:13:33So far,
01:13:34who has agreed with me?
01:13:35Tell me.
01:13:37We have not got the proof yet.
01:13:39We have not got the two outputs yet.
01:13:42But,
01:13:43till now,
01:13:44who has agreed with me
01:13:45that you can do this.
01:13:46You are not doing anything wrong.
01:13:47That you can give the same input twice.
01:13:50And,
01:13:51NAND gate's job is
01:13:52to gather these two inputs first.
01:13:54It will gather these two inputs first
01:13:55and then it will put it again.
01:13:57This time,
01:13:58you tell me,
01:13:59this time,
01:14:00if I call D Morgan,
01:14:02this A B bar,
01:14:03actually,
01:14:04you don't have to call D Morgan here.
01:14:05Brother,
01:14:06two same things,
01:14:07look,
01:14:08A B bar and A B bar,
01:14:09two same things,
01:14:10in Boolean algebra,
01:14:11if you count two same things,
01:14:12it will be one thing.
01:14:15That means,
01:14:16this is A B bar,
01:14:17this is A B bar,
01:14:18two same things.
01:14:19If you count two same things,
01:14:20it will be the same thing.
01:14:21That means,
01:14:22it will be one A B bar.
01:14:23There is another bar above it.
01:14:24Look,
01:14:26this is A B bar,
01:14:27this is A B bar,
01:14:28two same things.
01:14:29In Boolean algebra,
01:14:30if you count two same things,
01:14:31it will be the same thing.
01:14:33And,
01:14:34there is a whole bar above it.
01:14:35Now,
01:14:36two whole bars,
01:14:37cut off.
01:14:38Look,
01:14:39A B,
01:14:40A B,
01:14:41got together.
01:14:42Who understands,
01:14:43brother?
01:14:44These are very interesting things.
01:14:45That means,
01:14:46with NAND gate,
01:14:47AND gate has been realized.
01:14:48Look,
01:14:49AND gate's output,
01:14:52it counts two inputs.
01:14:53With this,
01:14:54if you count it,
01:14:55even through NAND gate,
01:14:56maybe you need two NAND gates here,
01:14:57there is no problem.
01:14:58You can use NAND gate
01:14:59to realize AND gate.
01:15:02Here,
01:15:03as many times you want,
01:15:04as many times you can bring NAND gate,
01:15:05there is no problem.
01:15:06But here,
01:15:07it is done by bringing two times.
01:15:09First,
01:15:10I will count A and B variables.
01:15:11Once I count it,
01:15:12it will count and fulfill.
01:15:13Then,
01:15:14I will put the same thing
01:15:15again in the NAND gate.
01:15:16Here,
01:15:17if you count two same things,
01:15:18it will be the same thing.
01:15:19And,
01:15:20there is another bar above it.
01:15:21So,
01:16:22Now, by NAND gate, OR gate, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait,
01:16:42wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait, wait,
01:16:52OR gate, listen,
01:16:54So, when you used NAND gate to activate AND gate,
01:16:59Brother, AND gate does the work of addition.
01:17:02And NAND gate does the work of addition by itself.
01:17:06First it adds, then it completes.
01:17:08So, now, when you will activate OR gate from NAND gate,
01:17:12If you keep going like this for one series,
01:17:15For example, if you take two NAND gates here,
01:17:17If you do it again and again,
01:17:19All your life, only addition will come.
01:17:21Only addition will come.
01:17:23Think in a cool way.
01:17:24Brother, if you keep going like this for one series,
01:17:27If you keep going like this for one series,
01:17:30What does NAND gate do?
01:17:32It does the work of addition and completion.
01:17:34It does not do the work of addition.
01:17:36So, if we keep going like this for one series,
01:17:39Will addition come?
01:17:41It will not come.
01:17:42So, it cannot be done like this in one series.
01:17:44So, what will we do now?
01:17:46See, understand a little better.
01:17:48Brother, we are studying for the purpose of NAND gate.
01:17:51In the name of NAND gate, there is NOT gate and AND gate.
01:17:55So, these two have become one series.
01:17:57But when we use NAND gate to activate OR gate,
01:18:01OR gate does the work of addition,
01:18:03So, for addition, two different NAND gates have to be started separately.
01:18:08See what I do.
01:18:10Wait,
01:18:11A and B,
01:18:12I will take two different NAND gates.
01:18:15See, this is a NAND gate.
01:18:18I will take two A's here.
01:18:22See,
01:18:23A went twice.
01:18:25Another NAND gate.
01:18:28This is a NAND gate, NAND.
01:18:30Again B.
01:18:32Listen, the input is one.
01:18:34How many variables are there? Two.
01:18:36So, I took two variables.
01:18:39I put two A's in this NAND gate.
01:18:42That is, this is also an A and this is also an A.
01:18:44So, what will be the output here?
01:18:46Two A's.
01:18:47Listen, understand well.
01:18:49This is A and this is also A.
01:18:51But it is not written here.
01:18:53It is not necessary to write A separately here.
01:18:55Because A and A are the same.
01:18:56They are coming from the same line.
01:18:58So, if this is A, this is also A.
01:19:00So, what will be the output of this NAND gate?
01:19:01Two A's will be there.
01:19:03And on top of that, an asterisk.
01:19:06And we know that if we do A and A, it will be A bar.
01:19:09Here, two B's.
01:19:11B and B will be there.
01:19:13Two B's and on top of that, an asterisk.
01:19:15We know that if we do B and B, it will be a BE.
01:19:17Now, see, we got two outputs here.
01:19:20We will put these two together in the NAND gate again.
01:19:23The math is over.
01:19:24You will get the answer from the math.
01:19:26Listen, understand well.
01:19:28If you keep going to the same serial as before,
01:19:31then you will keep coming to the work of the asterisk.
01:19:33You will keep coming to the work of the asterisk.
01:19:35When I do OR gate, I will need an asterisk, right?
01:19:39So, what did I do for the asterisk?
01:19:41There are two total variables.
01:19:43A and B.
01:19:44And there are minimum two variables in the NAND gate.
01:19:46That means, two inputs are required.
01:19:47So, in the beginning, in the NAND gate,
01:19:49I took one variable, A.
01:19:51I sent it twice.
01:19:53Then, two values will be there and the output will be there.
01:19:55If I do A and A, it will be A bar.
01:19:57Here, I sent B twice.
01:19:59If I do B and B, it will be B bar.
01:20:01This time, I put these two inputs in the NAND gate again.
01:20:04That means, the input of this NAND gate is A bar and B bar.
01:20:08So, what will it do in these two cases?
01:20:10What will the output do?
01:20:11It will do A bar and B bar.
01:20:13It will do the sum of these two.
01:20:16And it will complete it on top.
01:20:18Who can understand this?
01:20:19Tell me.
01:20:20Brother, understand well.
01:20:22This input is A bar.
01:20:26And this input is B bar.
01:20:28So, this NAND gate will do the sum of these two inputs.
01:20:31And it will complete it on top.
01:20:34This time, look.
01:20:35You do A bar and B bar.
01:20:37Take these two as A and B.
01:20:39A, B, whole bar.
01:20:40This time, you use the D Morgan formula.
01:20:43It will break apart.
01:20:45And it will merge in the middle.
01:20:47Look.
01:20:48It was a sum.
01:20:49It will merge.
01:20:50This time, another bar will come on top of it.
01:20:53B bar.
01:20:54Another bar will come on top of it.
01:20:55D Morgan formula.
01:20:56Take A bar as A.
01:20:58And take B bar as B.
01:21:00A, B, whole bar.
01:21:01One bar will break apart here.
01:21:03And another will break apart here.
01:21:04It will merge in the middle.
01:21:05So, the two bars are the same.
01:21:08Look.
01:21:09The output has merged.
01:21:10Who can understand this?
01:21:11Tell me.
01:21:12It is an easy thing.
01:21:16It is not difficult.
01:21:17Look.
01:21:18Brother.
01:21:19There is a ZARA in NAND.
01:21:21And there is a NOT in NAND.
01:21:22This NOT will be done once.
01:21:24The two NOTs will be the same.
01:21:27There is an AND in NAND.
01:21:29The NOT in NAND will be done twice in one serial.
01:21:32But the NOT in NAND,
01:21:34means OR gate,
01:21:35by NAND gate,
01:21:36can do the work of its own property.
01:21:39It can do the work of its own property.
01:21:40It cannot separate the two gates.
01:21:42In one serial,
01:21:43it will be done in one flow.
01:21:45But OR gate does the work of the world.
01:21:48And NAND gate does the work of the property.
01:21:50So, it cannot be done directly.
01:21:53The NOT has to be taken separately.
01:21:55The NOT has to be taken separately.
01:21:56The NAND gate has to be taken separately for the NOT.
01:21:58The NAND gate has to be taken separately for the NOT.
01:22:00And again, the same two NOTs,
01:22:01is NAND gate.
01:22:02End.
01:22:03Have you understood?
01:22:06Yes.
01:22:07Very good.
01:22:08So,
01:22:10I have taught you in today's class,
01:22:12the significance of NAND gate.
01:22:16The significance of NAND gate.
01:22:18And if we give it to other classes,
