PCM - Analog to digital conversion

PCM - method of analog to digital conversion
Introduction
Today my topic is Pulse Code Modulation or PCM- a method used to convert analog signals to digital signals.
PCM consists of three steps: sampling, quantizing, and encoding. PCM may sound very complicated because it involves many big words, such as pulse, amplitude, modulation, sampling, sample rate, quantization or quantizing process, bit depth, and so so, but it is actually a very simple process if you take it apart and look closely one step a time.
My topics are organized by playlists:

I know this is a 2yr old post, but I want to thank you for taking the time to explain this.
It has helped get me one step closer to a product I’m working on which may save lives in the future.

[@JoM934]

How goes the product?

one of the best teachers i ever came across. This is gold.

[@mehrdad1065]

Thank you. You are a good teacher. I watched a few videos prior to yours and understood NOTHING. You made it very simple to understand. God bless you.

[@onnguyen3408]

I have worked in major Digital Signal Processing, your video is the great explaination in PCM.

[@auctifer0]

Nicely explained, great animation and presentation. Please keep up the good work!

Such a clear explanation sir, i really appreciate it 🙏 better explanation than my professor

[@patrikmaryska]

Greetings, thanks for a great video, it helped me incredibly a LOT. I am a little bit confused with image digitalization. Does it work the same way as PCM? (we would not have only time on x axis but something different?)

[@MrLochay]

very very helpful. Thanks a lot.

[@hvh_music]

That's really helpful!

[@thecrowester]

I'm looking to connect my iPod classic to my digital audio preamp using an ADC. Will I be encountering any loss in audio quality by converting my iPod's line-out audio to digital using an ADC then connecting the ADC to my DAC preamp connected to my studio monitors? The ADC has a sampling rate of 32, 44.1, 48 and 96 KHz/48 KHz while the DAC has a decoding range of 16-24bit/ 32-192KHz.

[@ameerhussain2051]

Approaches can be different to different people, but your approach is understood. Love from Pakistan ♥️

[@sunnyclassroom24]

Thank you !

[@siou3268]

Excellent video.
One question.
What if a sample value does not match a specific bit value but corresponds to an intermediate value?
Where is that sample matched to the higher or lower bit value and is there any metric relationship to allocate the value to a bit?

[@imonkey1773]

Thank you so much! Keep it up

[@sunnyclassroom24]

You are welcome, and I will do.

[@ahmadkhateeb1351]

thank you really

[@numaanjaved]

Thank you for this very nice explanation

[@sunnyclassroom24]

You are welcome!

[@vasumathi805]

Thank you

[@dhruvinpatel684]

sir how you have used 8 bit depth value .. like that can we use any value?? ex 16 bit

[@ashasugumar1916]

Your explanation is very clear sir. Please put video for QPSK, QAM

[@alexandragonzalez5296]

How do I find what the data rate would be if the signal were being sampled every ms instead of every second?

[@Tardigradient]

Why are the vertical lines (sample rate) spaced apart in varying time intervals? If the horizontal axis is time, then a varying distance between samples means that the frequency of sampling occurs in unequally distributed intervals right?

[@miguelcarvalhoaraujo906]

Thanks for the video, it's great!
Note that "conversation" on the title should be "conversion" ;)

[@sunnyclassroom24]

Thanks a lot. I have corrected it and I appreciate it very much, Miguel.

[@PHamster]

Although, I enjoyed the Conversation about Conversion :)

[@qushaeiryzailani5118]

[@sunnyclassroom24]

Thanks a lot.

[@mikimauseontheway]

Are encoding is going to from (Right to Left or Vice versa ).. ??

[@T_vinitDagde]

I like it very easy to understand

[@sunnyclassroom24]

thanks.

super

[@orlando_kawaii]

"Great question! It depends", at 2:42 somehow sounded sarcastic to me lol.
Anyways, it was a nice video. Not kidding.

[@bhupeshpantguru8955]

Awesome

Thank you for watching! Check out my other videos please!

[@lanceuppercut8220]

He does a great job of explaining things in a way that really make sense. This video was the one that made me check out subscribe to the channel. There are a lot more great videos on this channel.

[@donmorris1373]

Very good explanation. Why Sir you was not making video when I was studying 😂😂😂

[@vidhyasasidharan3710]

Good class

[@sunnyclassroom24]

Thank you for your time!

[@umar812]

what an amazing explanation!
but, in quantization, what is the difference between every two levels in terms of volts?
I don't know if my question is valid but I have been watching other vedios and they talked about it.

[@-boiadeiro-]

you have to catch up these voltage diff w some device, that will know which lvl has specific value representation, in theory)))

[@stevenshelby2675]

This strangely was very understandable to me

[@DragonDHunter]

I cannot see the difference between quantizing and encoding. Both associate binary values to samples

[@asifshaikh-gn3en]

How video is converted into binary
