Digital modulation: ASK, FSK, and PSK

Last time, we talked about two analog modulation methods: AM and FM.
Today we will talk about three types of digital modulation: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK).

My topics are organized by playlists:

Amazing how this 5 minute video explained it so much better than my prof's material.

This is extraordinary pedagogy. You make it seem so simple, but the average person who is knowledgeable in radio wave technologies would be wholly incapable of communicating AM/FM/PM in such an accessible manner. Thank you very much.

Absolutely wonderful! I understand the concepts much better now!

[jashevan]

Keep creating these great videos. Your way to simplify complicated concepts to deliver key points are so helpful. Thank you so much.

[chinnichandhana]

u r simply awesome, i didn''t expect that u will teach the whole concept in 5min before opening this video, . Kudoos bruh

[manasbhardwaj]

Really great work you are doing while explaining these complex topics with so much simplicity, conclusively it gave me the confidence that it was merely a common sense. You are really a great teacher and you really have a deep understanding of the subject.

You are the man. Well done my friend. No cameras trying to focus and no ugly handwriting! Bravo. Great work.

[atesz]

Thank you! I wish that all the classes should be like this. Very well explained.

[shareenasahab]

honestly this is the best explanation. Thanks a lot!

[ericarcadia]

I dont usually comment on videos, but this is a great explanation. Keep up the good work. I'm a big fan of your explanations and visuals. Super helpful. Thank you!

Quick notes:
Modulation describes the process of representing digital signal in physical form.
ASK: High Aplitude writes 1, low amplitude writes 0
FSK: Higher Frequency writes 1, lower frequency writes 0
PSK: A phase change basically means a switch - you either switch to start sending 1s or 0s - you write the same value until you "switch" again

Sir, this is the best explanation ever. The PSK is so easily digestible now.

[HopeJustice]

When you see such a brilliant explanation, really students around the globe have no excuse not to understand any material, thanks so much

[lukaszwiktor]

Right to the point! Thanks a lot for the clear and concise explanation.

[verdiernoyama]

I am french and I have an oral exam in two days. Your videos about modulation are excellent. They will help me a lot

[andrewkina]

You're a great teacher Sunny! Thanks for simplifying this concept for me!

[shelbymedia]

It is amazing to something to get understand in a short period of time. Thanking You!

[aownme]

Been searching about these for many hours. But your's explanation is simply awesome. Thanks for the video :)

There's a lot of channels that really insightful like this, such a gem in the ocean of channels indeed
