Subject code is BEC101 obliq BEC201, yani ki agar ap first semester mein to you will follow the code BEC101 and if you are in second semester, second semester mein agar ap ye subject pahne ja rahe hai so your code will be BEC201 and here we are in lecture number 0.

So in lecture 0 we will discuss the first of all what is the syllabus that we have to learn and the respective course outcome that you will gain after going through the complete syllabus of the given subject.

So first let's discuss what is slabus.

So if you talk about slabus, the subject is a full-traded subject.

That means the slabus is divided into 5 units.

Unit number 1 to unit number 5 and you can say 5 modules.

So if you talk about unit 1, then unit 1 starts with semiconductor theory.

yiannay ki, sab se pehle aap loog dekhne waale ho p type, n type semiconductor kya hai kis tari se form huye and once you know p and n type semiconductor tab uske baad ham loog bana pahengue diode yiannay p and junction diode kaisse bana, depletion layer concept kya aya, aur vi characteristic ni ki diode ki working, aur kis tari se uski vi characteristic draw ki jati hai then you will learn about the topic ideal and practical diodes and then, once you know the diode in deep, then you will able to understand what is diode equivalent circuit, diode equivalent circuit means diode किस सरे से काम करता है कैसे हम circuit के अंदर diode को different different configuration में apply कर सकते हैं like reverse bus है, forward bus है so different different configuration के base circuit में current किस सरे से flow होगा वो सब आप लोग जानने वाले हो after that you will learn about the important application that is called rectifier half wave full wave rectification using with the help of diode after that clipper and clamper the main important two application based on diode after that हम study करेंगे zenad diode, तो zenad diode क्या है ZenR diode की क्या working है, operation है what are the different breakdown mechanics यो कि है ZenR और Avalanche दो type की breakdown mechanics है and the most important thing is ZenR diode as a shunt regulator or you can say voltage regulator किस तरह से हम voltage को regulate करते है with the help of this diode and in last you will learn about voltage multiplier circuit जैसे की नाम से पदा चल रहा है कि input voltage को मुझे multiply करना है either 2 time, 3 time, 4 time तो that is the circuit voltage multiplier circuit.

After that If I talk about the last part of the unit, then here we talk about the special purpose diode.

Like light emitting diode, LED, photo diode, verector diode, tunnel diode.

These are the different special purpose diode, which are working, construction, and VIA characteristics.

These are all about the unit number 1.

If we talk about unit 2, then unit 1 is where you have a diode.

After PN junction diode, the next form is called BJT and FET.

So, here you are going to study two special devices One is called the bipolar junction transistor which we will study again the same thing Starting from the construction, working, operation Then what are the different configurations of BJT which can apply in the government Like common base configuration, common emitter configuration, common collector configuration So, what does it mean in different configurations?

can apply?

Like Common Base Configuration, Common Emitter Configuration, Common Collector Configuration So, different configuration apply means what is BGT is our current amplifier device and when it is current amplifier device, then how much current amplifier is in different configurations that you will measure.

That is why the topic mentioned over here, Amplification Action There, if we talk about BJT second topic, this is your field effect transistor.

If BJT is current amplifier, then field effect transistor is a voltage amplifier.

So, same thing you will learn here, construction and working.

But, here you will learn two types of FET.

One is called JFET, that is called junction field effect transistor.

And the second one is called MOSFET, which is divided in two parts as depletion and enhancement type MOSFET.

So, if I talk about it here, you will learn simple, what is the working, construction and based on working, what are the characteristics formed in our FET.

So this is your complete second unit, if you divide in two parts, one part is called BJT, i.e.

bipolar transistor, and the second part is called field effect transistor.

Now after these two units, the unit number 3 that comes here, that is called operational amplifier.

Now if I talk about starting in both units, most of the time you have to get construction, working, operation, but if you will get in unit 3, when you reach operational amplifier, it is my favorite unit, because here I get a lot of mathematical, I get a lot of information about OpM IC What is OpM IC and what is used And using this OpM IC I can form different circuit Different amplifier Like I can make inverting amplifier, non-inverting amplifier, unit follower Somewhere I can make adder Integrator, Differentiator We can make such type of device Input quantity integrate, differentiator if you apply this input quantity then it will get the differentiation in your output end so that's why this is a very important and very easy unit straightforward topic and application you will get to get to the application when you go to op-em, you will study basic application and you will study characteristics there is one important characteristic that is called differential and common mode operation that in op-em there are two types of operations so what is differential mode, what is common mode we will know and a very easy and very requirement property that is called comparator that in which way we can compare two quantities with the help of this op-amp IC so this is a very small and very easy and mathematical unit that is called unit number 3 so after this unit the next unit is also very easy and that is called digital electronics unit number 4 so digital electronics can start with number system, number system, representation, different type of number system how we represent and how we represent and how we convert one number system to the other number system.

In that way, you will see what are the basic logic gates and what are the universal gates and how I use these gates to develop my circuits.

After that, you will come under the simplification of your Boolean function.

Boolean function for simplifying two methods One is called the Boolean algebra and the second one is called the K-map or Karnoff map.

So, using both methods, we will learn the minimization of given Boolean function.

And if I talk about the syllabus point of view, then here on the minimization, you have to learn the K-map, 4 variables available, 5 variables available, up to 6 variables in your syllabus.

So, 4 variables K-map, 5 variables K-map, 6 variables K-map, this too.

And if I talk about the theory point of view, then again, this unit is not theoretical.

This unit will get a numerical point of use, a mathematical kind of unit.

So this needs a practice.

Now, after this unit, if I talk about last unit, then again this is some kind of mixed unit.

That is, here theory also.

Some numerical also there.

So, unit is called fundamental of communication engineering.

That means you are going to learn from here.

What are the basic elements used in a communication system?

So, when we talk about this, first of all, we will need about what is signal.

How do we represent the signal?

How do we analyze the signal?

then we will understand the basic elements of our communication system.

When we talk about communication, there is a very important term that is called modulation.

What is modulation?

Why is it important?

What are the typical applications of this modulation technique?

If we talk about modulation, amplitude modulation is a part of it.

So, the fundamental of amplitude modulation and demodulation techniques are what are they?

What is the type of modulation and demodulation?

We will learn in these demodulation articles.

learn in these demodulation and modulation techniques of this part 1 of unit number 5.

If we talk about the second part in unit number 5, here we have Introduction to Wireless Communication.

What are the standards of wireless communication?

How do we do wireless communication?

What is cellular communication?

What are the different generations and the standards used in cellular communication?

Like our GPRSA standard, GPSA standard, CDMA standard.

So what are the different standards?

what are the different generation, first generation, second generation and last you will learn about the satellite and radar communication what are the elements in them, what are the fundamental elements look at the main thing in communication transmitter receiver but transmitter receiver side which element is different in our communication like in simple example wire communication transmitter and receiver dedicated wire apply but there is wireless so there is no dedicated wire but somewhere else there will be no channel so that transmitted data receiver can reach to the receiver so it has different communication medium which will gain fundamental knowledge so this is all about complete syllabus now if I talk about syllabus there is books so if we talk about books first of all the common books and the concept that you will understand in voice state will be very good and for this reason, you have mentioned many books in your syllabus so as it is, I have kept a book in your syllabus you can refer to any book but the concept you have question apply from any book apply the same concept and check whether you are getting the solution or not.

After books, the next topic is course outcome.

What are the outcomes and objectives that I am learning from Slabers?

If I talk about Slabers, then unit number 1, when we go through, you can say that you are able to describe the concept of P-injunction and the respective devices.

Different special purpose devoid you will study.

So we can say that you are able to describe the concept of P-injunction and the special purpose devices.

So, I will say that when you are using BJT and FET, then you can be able to explain the concept of what is BJT, what is MOSFET, what is FET, junction field effect, MOSFET, what is BJT, what is their construction, what is it?

We can explain all these things.

If we talk about unit number 3, that means operational amplifier, so once we learn through the operational amplifier, we can say that you are able to apply the concept of operational amplifier to design linear and non-linear applications.

application, non-linear application when you go through this unit you will learn all these things how can we use operational amplifier to design these type of applications from the unit number 4 we can say that we learn the different types of number systems, their conversion how to convert the binary arithmetic and minimize the logic function, how can we solve binary arithmetic 10 plus 10 everyone knows that it is 20 but it is in decimal number system but if you say binary addition or octal number system addition so that you can explain after going through this complete unit and after unit number 5 once you go unit number 5 or once you complete unit number 5 then you are able to describe the fundamentals of communication technologies different communication technologies what are the different standards that you can explain so these are the objective after going through the complete syllabus so it will be about the syllabus books will be about the course outcome now what is the upcoming lectures So upcoming lectures में जो मैं start करूँगा I will start in the same manner कि मैं unit number 1 को start करूँगा then unit number 2, then unit number 3, unit number 4 and unit number 5 So same manner मैं आपको भी suggest करूँगा कि जब भी आप इस subject को start करें So unit number 1 and 2 especially एक साथ करें because unit number 1 में जो आप PN junction and out concept समझेंगे वही आपका BJT में भी apply होगा working किस तरह से चल रही है अगर मैं unit number 3 or 4 की बात करूँ तो यह दोनों separate हैं, आप separately use कर सकते हैं, 3 is an operational amplifier आप बिलकुल separate मान के से solve कर सकते हैं unit number 4, digital electronics कभी भी कहीं से भी start कीज़े digital के concept उसी के अंदर है and unit number 5 की अगर मैं बात करूँ communication concept, तो communication concept be a separation.

So, unit you can do any fashion in any fashion.

Dependency is not here.

Some of the dependencies you can cover in that topic.

But if I have a suggestion to start in the same manner, unit number 1, unit number 2, unit number 3, 4 and then 5.

So, in this manner, I will start with you this subject and I will get the next lecture with the first topic of unit number 1 that is semiconductor theory.

So, we are made with you.

See you in the next lecture.

Thank you.
