one thing you can highlight is that the Carrier wave is sampling the signal m(t) so AM is by its very natue lossy/interpolated-between the peaks of the carrier

What happen's when your modulated signal is composed such as m(t)= 2Cos(400t)+4Sin(500t+pi/3) that mean that the Am is 2 ? what about the Omega and the phase shift ?

Sir I can not understand why the AM modulated signal looks like this.And why we are adding the amplitudes of messege and carrier like,A'=(Ac+m(t)) this.plz help me

Sir... For plotting frequency response, we need to apply fourier tramsform.. But you took the same timedomain amplitudes as frequency domain amplitudes which may not be equal...
There is nothing wrong in that. Fourier transform is one method of plotting the frequency response of a time domain signal but it's not the only method we currently have. In above video,signals of constant frequency has been taken as an example so we can directly plot the frequency response by intuition, ie. an impulse of amplitude same as signal amplitude at a frequence 20Hz(example). If you look closely above frequency response is discrete in nature and can be obtained mathematically by Fourier Series.
@@narasimhal1 It's not clear what you meant by "differ from visualization". Don't make it complex than it looks. Just apply phasor diagram or apply euler's theorem.
Sketch the specturm of modulating signal m (+) given by a.m (+)= cos 2pi ×3×10^3t+ cos 8pi ×10^3t B.cos2pi×10^3t x cos2pi ×4×10^3t Plot the two sided amplitude spectrum in both cases
it's looks cumbersome if you look those components in sinusoids. Better convert cos components into exponentials using Euler's theorem and then use time shifting property of fourier transform to convert those into frequency domain Then you can have frequency response in 3 steps
I think amplitude is changing w. r. t. Time therefore we can't just add amplitude bcoz it's not fixed so that we can add it but it is changing with time hence we have to ad while equation

Sir, In the amplitude vs frequency plot, one amplitude is negative for the frequency wc+wm. Shouldn't we consider that while plotting? If so the sidebands will lie in 2 different quadrants right!

00:02 Explanation of Amplitude Modulation
02:29 Amplitude modulation involves changing the amplitude of the carrier signal with respect to a modulating signal.
04:39 Amplitude Modulation involves changing carrier signal amplitude with message signal.
06:52 Amplitude modulation is represented by the equation AC(1 + mu*sin(OmegaMT)*sin(OmegaCT)).
09:58 Amplitude modulated signal has three frequency components.
12:40 Amplitude modulation involves carrier signal, side bands, and waste of power.
14:52 AM has drawbacks like higher bandwidth and power requirement
16:42 Amplitude modulation involves sending carrier signal and sideband signals.

I have a confusion..
In the frequency response, the amplitude, wouldn't that be πAm/2 for sidebands?
Its perfectly correct in this video.
Then sir, when we find the fourier transform of the signal and plot the frequency response, isn't the amplitude of sidebands πAm/2 ?
Ohh sorry, u've shown the frequency response using Fourier Series isn't it?
13:44
You represent the y(t) in three discrete cosine wave. By fouier transform it transfers to delta function with amp= pi*mu*Ac/2 , rather than just mu*Ac/2?
and also there are -Wc-Wm, -Wc, -Wc+Wm in negative side rather just positive side ?

thank u for your efforts
Sir I can not understand why the AM modulated signal looks like this.And why we are adding the amplitudes of messege and carrier like,A'=(Ac+m(t)) this.plz help me
In AM, we need to change Amplitude of carrier signal with respect to modulating signal.
majja agya, Good Explanation!
very helpful. thank you Prof.
Love and happiness of students is my ultimate goal, God bless you 🙏, keep learning and keep progressing.
Tqew sir best explanation

sir Ac is there ,why did you write just A ? at 11:20. please clarify
At 12:00 it is already explained
@@EngineeringFunda ok thank-you sir
Great explanation, thank you
Glad it was helpful!
Superb sir....

thank you for making video. it is so helpful me
Sir... For plotting frequency response, we need to apply fourier tramsform.. But you took the same timedomain amplitudes as frequency domain amplitudes which may not be equal...
It is there in frequency domain only
See practically it will slightly less then theoritcal but I have shown it correctly
There is nothing wrong in that. Fourier transform is one method of plotting the frequency response of a time domain signal but it's not the only method we currently have.
In above video,signals of constant frequency has been taken as an example so we can directly plot the frequency response by intuition, ie. an impulse of amplitude same as signal amplitude at a frequence 20Hz(example).
If you look closely above frequency response is discrete in nature and can be obtained mathematically by Fourier Series.
@@pranavc4397Frequency Response (Magnitude and Phase spectrum) are differ from visualization of signal strengths at their oscillating frequencies!
@@narasimhal1 It's not clear what you meant by "differ from visualization". Don't make it complex than it looks. Just apply phasor diagram or apply euler's theorem.
thank you sir..good teacher
The videos are randomly presented which doesn't makes the continuous classes😶
But the teaching style is osm👌
Sketch the specturm of modulating signal m (+) given by a.m (+)= cos 2pi ×3×10^3t+ cos 8pi ×10^3t
B.cos2pi×10^3t x cos2pi ×4×10^3t
Plot the two sided amplitude spectrum in both cases
it's looks cumbersome if you look those components in sinusoids. Better convert cos components into exponentials
using Euler's theorem and then use time shifting property of fourier transform to convert those into frequency domain
Then you can have frequency response in 3 steps
Harsh gupta wow you really know your stuff can you please help me with some questions please about RF
6:34 ....u should add only amplitudes...
But why did u add (amplitude +whole signal)
Its Amplitude Modulation
@@EngineeringFunda i didn't get it
I think amplitude is changing w. r. t. Time therefore we can't just add amplitude bcoz it's not fixed so that we can add it but it is changing with time hence we have to ad while equation
thank you soo much !!!

As the upper sideband compoent is -Ac mu cos(Wm+Wc)/2 , why the amplitude is +mu.Ac/2 at Wc+ Wm?
Sir, In the amplitude vs frequency plot, one amplitude is negative for the frequency wc+wm. Shouldn't we consider that while plotting? If so the sidebands will lie in 2 different quadrants right!
Thanks Sirji

Thank You very Much
Your welcome
Sir please upload a video of "amplitude modulation generation using amplifier circuits".
Asif Ahmad sir please can you help me with some questions? About radio frequency’s
Very useful explanation (y)
Your positive comments motivates me, Thanks and welcome 🙏
sir i have seen in books that using...
m(t)= Acoswt instead of Asinwt....
whats the difference??
No difference, you can take any of sine or cosine.
how will be the derivation like sir, by using cos??@@EngineeringFunda
It will be same as what I have done. So don't worry about sine or cosine.
This was great! Thank you!
You're so welcome!
is it needed to greater the carrier amplitude than message amplitude?
Nope. It just shows over modulation and under modulation
Nice explanation

great video..

thankyou for making me understand this !
