i had a doubt, if anyone can help ..thank you .... doubt- at 22:30 , when fourier transform of modulated signal m(f) , is represented in positive and negative frequency sides , and amplitude of that spectrum is halfed then, how can bandwidth remain same to that of bandwidth of m(f), as shape of spectrum must remain same , but if bandwidth doesnt change and amplitude is halfed ... then shape must be changed .. i think....

Great video follows the BP lathi Communication principles book.

armstrong method

such an elegant explanation. a must watch. why do our teachers make these beautiful concepts into such a tragedy, eventually leading us to hate the subject

nice explanation sir

Why we are not measuring ESD of this random signal ?? Anyone pls clarify it

Harami master.......

sir looking like baba ilaichi. BTW, excellent teaching

Sir I request you make a playlist of all the 60 classes in the order so that we can simply play them in order Thank You

I had watched another lecture and read the material in the book. There I was forced to take these equations and deductions for granted. For the first time I understand Fourier Series in an intuitive level and why it is so elegant.

But I am watching these lectures before end sem in the last 2 days with 2x speed 40+ lectures

I took everything you taught in this course , thanks and god bless

thanks soo much😊

Follow BP lathi after listening lectures

No words to describe the knowledge....

Sir n >beta +1 how

Really invaluable and priceless explaination of the famous Fourier Series..which I could’nt find anywhere until now

yeh padhke bhi SJ ko dene to 2 number hi hain

great teacher ...

This playlist is probably the best playlist for analog communication to understand from the basics. There is no other knowledge like this teacher has provided. Thank you so much..

Such a clear explanation and making us understand from ground level. This is lit.

R.K.B. iska full form jaan na hai toh btao

Complete representation of B.P.Lathi

I must say he is one the best communication teachers I have ever seen

Sir u have mistakenly stated energy signal in place of power signal ,while explaining Parseval theorem.

Nothing in this world can buy this lecture or compare..this truely magnificent

no wonder scientist have so much trouble understanding it. thiis is insane topic....

This teacher is a pure gem !

Wow!!! Other teachers, just let this! This! This! And you get this. But Sir, first proove it this is because, how it works, we let it because it is like this. Really amazing... 💗

I think My teacher didnt even know that in Analog communication, there is probabilty topic.

Getting more and more complex😵😵 is this much consideration needed to overcome noise. Communication is difficult

I am really enjoying these lecture😍.

Crystal clear now

14:45 the value here is different and at 23:15 the valu of Cn and C-n is different. Can we use this as we want?

The diffference between him and my teacher is like God and human. Human cant explain the whole universe. But god knows everything about the universe. All we need is dedication and patience to learn from them. Thanks a lot for these lectures

This is totally mind blowing...tomarrow is my exam but i am totally enjoying it. I wish if i get these videos more sooner.

Amazing Explanation

thank u so much sir, This series helped a lot

if we modulate signal we automatically increase it freq and energy is directly proportional to frefrequency but here it is said that energy is halved.. confused

09:17

Thank you sir

thank you sir

Wonderful lecture sir. You are the best as always. I'm proud to be your student at IIT kgp. 🙏🙏🙏🙏

thank you sir

Great ❤️

great lecture:)

thankyousir:)

Thank you, Sir.

thankyousir
