The exact video i was looking for. I previously saw your 2 videos (pulse shaping and What is ISI). But i was suprised, why Nyquist's ISI criterion works, and there you are thanks a lot Professor
I did a couple courses in DSP in college, and it was the most challenging subjectt of all the scientific fields. I always felt so dumb , and i did really invest in this i read tons of books on DSP. Anyway, I began to recently have a use for it, so i started studying it again, but your channel has make it a lot easier. You explain very well, very clearly I wish I had found your content when i was studying this. I still find this very hard, and people in this field are actually genius.
at 5:40 you have talked about in future compression i.e end to end delay what is that about is there any video available on your channel , can you give some insigts of this concept
This is the same as in pulse shaping, where the energy from each data symbol is spread out over multiple symbol time slots (in order to constrain the bandwidth), and at the receiver, all of that energy needs to be collected at a single decision-time in order to make a digital detection of that symbol. This video gives more details on pulse shaping: "Pulse Shaping and Square Root Raised Cosine" ua-cam.com/video/Qe8NQx4ibE8/v-deo.html
Is there any definition of "interference"? It refers to transmission in the same frequency that aren't for the receiver. But what is with slightly different frequencies? Is that interference too? It is a more general question. Thanks a lot .
Signals that are out of the frequency band of your receiver will be suppressed by your receiver front-end filter, so they will not interfere - unless your filter is not very good.
Thank you so much, it is the third semester in a row with you saving me from failing :)
That's great to hear. I'm so glad I've been helping!
Haha.
I have recently found your channel and I like your practical ways of explaining concepts. Very useful for Communication engineering students.
Thanks for your comment. I'm glad you're finding the videos to be useful.

I'm so glad you're finding the videos helpful. It's always great to hear from people who like the way I've explained things.
I did my course of electrical communication some times ago, but a good revise is always the right choice! Thank you so much and really good video!
That's great to hear. I'm glad you like the video.
It is super helpful! The best explanation I've found on the Internet.
Thanks for your nice comment. I'm glad it was helpful!
Your videos are helping me so much as I prepare for my final. Thank you!
I"m so glad you're finding the videos helpful.
good tool for exams preparation , thnx sir .
I'm glad the video helped.
Very clear video ! Thank you sir
