10. Pulse Code Modulation - Digital Audio Fundamentals

Pulse Code Modulation is an encoding mechanism, a way of representing digital data for the purposes of transmission and storage. But what form does this encoding take, and why is it needed? In this video, we'll explore the the concept of encoding and modulation as a corner stone of digital audio. We'll start from first principles and discover different modulation strategies and their advantages, and naturally arrive at why PCM is so resilient and has survived the test of time.

I've already seen quite a few videos and am really impressed, both by the content explained and the quality of the explanation + graphics quality. I really hope you'll get the recognition you deserve for all the efforts you put into this!

[alfredbasi]

I've seen quite a few videos on PCM but was unable to wrap my head around all these concepts until now. Your explanation was really informative and easy to understand, thanks!

[Sams]

wow, I'm up late watching videos and this gem shows up! Still surprised you don't have more subscribers!

[khanhhuyen]

incredible, animation & the way you put the problem and explain it

[DavidHughesss]

OK, I am trying to hack something together using I2S and I'm really glad I came across this. I feel like I'm at least starting to understand what I'm supposed to be doing now. Thank you so much!

[nelizevanschalkwyk]

This video's illustrations are so satisfying to watch

[dadominicanstyl]

Amazing explanation, the clarity of how you present the subject it is the best I have even seen! Thank you so much.

[blakemartin]

this playlist is incredible. Thank you for your contributions to the distribution and improved communication of knowledge!

[hendrikoffermans]

I agree, I am watching all videos on this channel and the level of explanation is so high (I am a teacher myself).. really amazing that this channel has so little subscribers.. excellent work! Thank you very much for your great videos.

[hawthornrabbit]

Fantastic video, this really helped me to understand frequency modulation and PCM like nothing else has.

[snowboarder]

Absolutely incredible. Such a good explanation. Thank you!

[Samplevideo]

BRO 17k AND SUCHH GOOD PRESENTATIONS, goddamn it man, love your videos

[Apoorvpandey]

phenomenal explanation, the touch of real example values made this even better!

[antoinedevldn]

I cannot understand why these are not more popular than this

[brydon]

By far the best video I have seen on the subject. Thanks a lot!

[rogo]

Such a simple explanation, you can just take it and code for something. Thank you!

[marktrivette]

This dude does excellent videos, breaking down complex EE that a layman can understand. Nice work.

[paveldroo]

This is simply excellent content, thanks for your work!

i've been searching for a video like this in german but still ended up watching this. This was a great help though, thank you!

[MahmudurRahman-emmn]

OMG what was that! This channel will take 'youtube study tutorials' to a whole new level. I mean Its been 3 years I am totally dependent on youtube for my engineering degree 😅and have watched thousands of tutorials, some of them were best, but today wasn't having a good one on PCM and found this channel and I am SPEECHLESS! Bro thanks for providing these for free! Dhonnobad❤‍🔥
just saying, I think you need to work on the thumbnails for these awesome tutorials otherwise it looks just like a boring ppt slides!
