Hello EzEd Channel, Great explanation and animation, straight forward, congratulations for this! Only some adjustments would be needed for wrong info: 5:26 wct instead of 2wct, because w=2pif. Error now is propagated until 5:45 At 6:56 fm=10^3, Ec=40, but the next must be corrected: 7:32 fm=10^2 and at 7:58 Ec=20 (F). Also at 22:40 the expression should be corrected in (wct). Wish you great lectures and keep going!
At 5:27 in the trigonometric identity is 2cosAcosB = cos(A+B) + cos(A-B). We know cos(-theta) = cos(theta). So it is mathematically valid to write cos(B - A) instead of cos(A - B). If we do so then eventually we will get (wm - wc) instead of (wc - wm) and finally the bandwidth will be 2*fc instead of 2*fm. As we are getting two possibilities mathematically hence we cannot just ignore the alternate one. But so far I have never seen to use 2*fs as the bandwidth instead of 2*fm. But we are getting it mathematically. So what is the significance of it?
Correct me if I'm wrong, but in the equation shown at 5:35 the [ Ec cos (wc t) ] part should be [ Ec cos (2wc t) ] . Otherwise the video is really helpful!
Please don't put in ads in the middle. They are distracting. When I am concentrating, suddenly an ad comes up, and I get a shock. Please don't do that. An ad in the beginning should be good enough.

I'm curious why no one has made a comment on this video. This guy presentation is amazing and extremely well done. Thank you very much
You proved to be a light for me in this dark topic.

There is an error around the 8:00 mark where E(c) should be 40 but is written as 20.
Correction:
Frequency Spectrum of AM wave:
eAM =......
cos(wct)
This video helped me understand a lot of key-things. Thank you!!!!!!
there is a mistake at lecture time 5:29 i.e cos2wct....it must be coswct
Thank you very much for your explanation, the best I hav heard

It is awesome . Thanks for this video.
Very well said. Kudos!
Example at 8:00, fm should be 100 Hz, not 1000 Hz, yes?
10^3 is 1000 ... why would it be 100 hz ?
In the problem definition, fm=10^3=1000 Hz... wrong notation in the solving
clean exaplanation👍👌👌👌
@8:06 : Ec=40 ; and (omega)Wm = 2pi* 10^3=1KHz
such a awesome video ...thanks
Correct me if I'm wrong, but in the equation shown at 5:35 the [ Ec cos (wc t) ] part should be [ Ec cos (2wc t) ] .
Otherwise the video is really helpful!
which software you use to make these types of videos??
Hi, Could you allow in the settings of this video the addition of new subtitles ? I want add a Portuguese version.
Hi +Alan. Please email us the file and we will add the subtitles to the video.
nice explanation sir, thanks for video, can you please uploads more videos on analog and digital communication
thanks uuhh sirrrr....soo helpful
helped in my mains paper

7:39 what? it's 100Hz... since wm = 2pi*100...????????????????
Right...? I feel crazy that isn't mentioned more in the comments?
amazing explanation....
Very helpful!
very helpful.
superb video
Dude, your derivation of AM freq spectrum got a notation mistake, 2Πfct must be wct
You Are The Amazing One

Great lecture for college students
can u provide pdfs for the analog communications
+Cherry, Please visit our website www.ezed.in for course content which includes notes.
You do not describe the Phase Modulation briefly.Please do it.
excellent
Epic video
an image is analog? i dont think so....
everything was beutiful until you mentioned the mathematical formulas.
nicley explained
