Professor knows that we dont know a thing. He slowly introduced it and explained every bit in detail. He taught like he's teaching a student and not talking to a phD you very much Sir!

Sir the way you introduced amplifiers is very appreciable
It created enthusiasm within
Thank you sir 🇮🇳👍

Thanks for the video, nowadays we take electronics device for granted, when the professor explains about the hard drive concepts. As a designer, I was thinking how huge engineering effort would have been spent to realize the concept. Thanks for all the great minds of physics, electronics, mechanics..

Will comeback for clarity / questions

9:40 Noise is a high frequency jerks of your signal. When you amplify the i/p signal, wont the noise too amplify? Does the 'amp' sub circuit contain in itself a *low pass filter* ?

9:43 So I think i got it. Does that *system* refers to A/D unit or Sensor unit? If it is A/D unit it makes sense, you make i/p volt. high thus making noise produced by A/D unit *negligible in comparision only* ?

12:47 'much more economical' :) how so?

37:30 *'DC power to be translated to the frequency'* meaning !? Straight from net,
Frequency translation is the process of shifting a signal from one frequency to another, without loss of information in the signal.

So i think to the external dc (which has 0 frequency) we add some sine waves, hence giving it some frequency.

Such a great introduction. Invokes curiosity, explains fundamentally.

Super, Thanks a lot sir for your way to deliver the lecture and core knowledge of Analog Electronics.
I wish i will watch your complete lecture series on Analog and make my base strong.
You are my second "Behzad Razavi".

Amplifier can be maid through passive components by decreasing the resistance by adding a bigger cross sectional area wire which will reduce its resistance.

Could someone please explain to me the reason why we need to have nonlinear elements in the amplifier? I didn't quite understand his explanation. Is it because in this case we'd have a Frequency of 0 Hz at the output --> DC Voltage, because of the Battery Voltage supplying the amplifier? Thanks!

Hii sir your teaching is awesome...
Can you please explain how you derived maximum power in load ...@ 29:20

polubalaji

nyc sir....!!!.but voltage source and current source are non linear.isn't it???

thushar

Thank you for your beautiful lecture. Just one doubt:
Max. power at R_L = [vo/sqrt(2)] * [vo/sqrt(2)] / (2*R_L) = vo/(4*R_L);
how another 2 is coming in the bottom Sir? Please rectify me.
