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
This video helped me understand a lot of key-things. Thank you!!!!!!
You proved to be a light for me in this dark topic.
Correction:
Frequency Spectrum of AM wave:
eAM =......
cos(wct)
Thank you very much for your explanation, the best I hav heard

Very well said. Kudos!
It is awesome . Thanks for this video.
such a awesome video ...thanks
There is an error around the 8:00 mark where E(c) should be 40 but is written as 20.
amazing explanation....
Very helpful!
thanks uuhh sirrrr....soo helpful
helped in my mains paper
nice explanation sir, thanks for video, can you please uploads more videos on analog and digital communication
clean exaplanation👍👌👌👌

superb video
excellent
Good explanation ..
sick editing :-D

Great lecture for college students
Epic video
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.
which software you use to make these types of videos??
there is a mistake at lecture time 5:29 i.e cos2wct....it must be coswct
You Are The Amazing One

Dude, your derivation of AM freq spectrum got a notation mistake, 2Πfct must be wct
Thank you

@8:06 : Ec=40 ; and (omega)Wm = 2pi* 10^3=1KHz
can u provide pdfs for the analog communications
+Cherry, Please visit our website www.ezed.in for course content which includes notes.
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
an image is analog? i dont think so....
You do not describe the Phase Modulation briefly.Please do it.
heh the squidward meme was right here
everything was beutiful until you mentioned the mathematical formulas.
7:39 what? it's 100Hz... since wm = 2pi*100...????????????????
Right...? I feel crazy that isn't mentioned more in the comments?
Pdf please

There’s a mistake!!!
