Frequency domain - tutorial 10: modulation

[@shahlakhalid8806]

Much thanks , because of you I have not only understood the subject but also I LOVE it.

[@Kuchdelan]

I love your comment, Shahla :) It is an absolute pleasure to help!

[@BVB1017]

i completed my batchlor degree, but this 22 min video gives a clear thougt about modulation and demodulation...... tq tq very much for helping us........

[@Kuchdelan]

Thank you for your feedback and it is my pleasure to help. Cheers!

[@fannierioux-gauthier5057]

Your jokes and your energy is so refreshing ! Learning doesn't have to be a pain, thanks to permit that :D

[@Kuchdelan]

It is a great pleasure to ease the learning process for you. Cheers!

[@shafagh_projects]

I just simply can say "It´s Wonderful!". You made the great tutorial on modulation.

[@Kuchdelan]

Thank you very much Shafagh!

[@shabazakhtar8809]

Thanks Iman, great work. I am revisiting signal processing theory after many years. Your videos have made my life much easier. Would be much appreciated if you can start adding videos for some advance topics. Many thanks.

[@Kuchdelan]

Hey Shabaz. Thank you very much for your feedback. Which topics are interested in? After I finish this course, I will most likely start digital signal processing. Please stay tuned to my channel. Cheers!

[@fmfreeze]

​@@Kuchdelan Thank you Iman for your great videos! As you mentioned here two years ago, did you ever realise a digital signal processing course? Cheers

[@lostlost6532]

@@Kuchdelan Did you started the digital ignal processing ? I hope you continue in this series and make more videos about image ,video processing and telecommunication .....I'll be grateful

[@dvoorganisation459]

Nicely Explained Many of my doubts cleared!!!!!
Thanks

[@Kuchdelan]

thanks a lot, pleasure to help ;)

AZAMING TEACHING SKILLS THANKS FOR SHARING . I LEARNED SO MUCH

[@Kuchdelan]

Glad you liked them!

[@dzed172]

You just awesome man thank you for all the hard work and the high quality cours can't thank you enough

[@Kuchdelan]

Thank you a very much! You are awesome too ;)

[@agostinoi4485]

Thanks a lot for this playlist!! You are a very good teacher!!! Greetings from Italy ;)

[@Kuchdelan]

Thanks a lot, my friend. You are amazing. Salute ;)

[@prantapr2040]

Namaste, Imam. Can you tell me how you made the representation of modulation and demodulation of the audio signal?

[@Kuchdelan]

I used MATLAB.

[@y031962]

Hi Iman, thanks for posting this clip. I was wondering what kind of software do you use for drawing, thanks?

[@Kuchdelan]

I build my own software called Castofly which will be available soon for the public. For now, check out www.podofly.io

[@hussainmayouf5835]

Great explanation 😍
Thank you 👌

[@Kuchdelan]

THANK YOU ;)

[@LandonM1997]

Your videos are amazing! Thank you

[@Kuchdelan]

Thank you very much, Landon ;)

[@Lestibournes]

10:12 - why don't we just divide z(t) by the cosine function to get x(t)? Wouldn't that be simpler and easier? Is it just because of dividing by zero?

[@Kuchdelan]

In practice, the division doesn't work and it is not mathematically correct (dividing by zero)!

[@durghamghanim4522]

Thank you very much.

[@bigm6470]

Great job! Thank you!
May I ask a question? What do it mean negative frequencies on your plots? How can you interpret this point? How do it influence on physics? For what do we need negative frequencies?

[@Kuchdelan]

thanks a lot for your feedback. Regarding negative frequencies, you might find the following link very useful:
en.wikipedia.org/wiki/Negative_frequency

[@khd_edu]

KFUPM students are thanking you Iman

[@Kuchdelan]

Pleasure to help :)

[@pkl520]

u are awesome~!! by the way, can you tell more about amplitude modulation and frequency modulation? big thanks~!

[@Kuchdelan]

thanks for the feedback, u are awesome too ;) "In amplitude modulation, the amplitude of the carrier wave is varied in proportion to the waveform being transmitted. This technique contrasts with frequency modulation, in which the frequency of the carrier signal is varied" (from en.wikipedia.org/wiki/Amplitude_modulation)

[@Kuchdelan]

this picture is really useful to understand the difference between AM and FM:

[@shiridiyenninti9066]

sir...what power and energy spectral densities in FFT tells us...

[@Kuchdelan]

Hey. The power spectrum tells us the portion of a signal's power falling within given frequency bins. Hope this helps!

[@DerpsterIV]

>Give me the energy to sleep less
Uhhh that's no good. Please sleep properly.
Thank you for the tutorials.

[@Kuchdelan]

Lol! Glad you liked my tutorials.

[@lefterislefteris2922]

The best

[@theory_behind]

I like you man
keep going

[@Kuchdelan]

thanks a bunch for the support. I will keep going for sure ;)

[@jawadwazir680]

Damn... You still there

[@abdellahsellam912]

How you doin? hhhh, great video👍

[@Kuchdelan]

Lolll! Thanks for your support
