Digital vs Analog. What's the Difference? Why Does it Matter?

What's the difference between digital and analog, and why does it matter?
Also which spelling do you prefer? Analogue or Analog? I couldn't decided so I bounced between them.

I like how you tricked me into understanding how binary works at the beginning.

I learn more on YouTube than school. Good video.

Wow, I really think this is the best explanation of analogue vs digital signals. Really good job with the analogy about the multiple light switches and the color spectrum. I finally get how analogue is continuous moving on a set gradient by only set increments, while digital can be customized into the most minute or miniscule settings possible.

I felt like this video implied that analog systems have effectively infinite resolution, which is objectively false. Per dollar, digital systems tend to have dramatically higher resolutions than analog. So even though they're discreet (pixels), the discrete information is so much infitessimally smaller than the information of a similarly priced analog media that way more detail can be retrieved from digital.

Also, pixels don't need to be square. And for music for example, the digital wave is just the slalem points through which a generated sine wave is swept, so it is as infinitely continuous on the analog end after the DAC as a pure analog audio signal.

By dodging the issue of the superior resolution of digital systems per dollar for each media type, it leaves some very bad impressions of the practical performance advantages of digital media in almost every single way.

I teach computer repairs. and this video saves me a lot of work in explaining this concept. This guy clearly is the best at what he does.

[Hellrun]

This is the clearest explanation I have seen given before

[dizzland]

I learned so much with your video that 15 years of working with computer didn't. please keep up the good work

[BoKKeR]

I have checked two other videos trying to explain the topic to my friend. But they all missed the mark. This video is very clear to understand. Thanks!

[vahidkamyab]

Best and easiest educational video to digest that I've ever seen.
I was pleasing to watch, thanks.

Love this video. Been teaching for many years and this really gets to the endpoint.

[lakshyapratapsingh]

Brother thank you very much. I even searched for analog computers but didn't find any informative video like yours but you are best.. You 🥰🥰cleared my doubt in simple language👄💬this channel must have more subscribers

[ham]

Wow, that was a very good, clear and easy way of explanation to Digital and analogue differences. appreciated

[puggeele]

Really nice explanation. I will definetely use it in my IT class, thank you.

[pallavi_chandaka]

Thank you for making this kinda videos!
These are awesome 💫

[edwardreichard]

I like this explanation of the two, well done!

[atousa]

your explanation lighted up my mind! thank you so much! ♡

You are a bit misleading about how digital audio works: It is indeed sampled in discrete steps in both amplitude and time (at least in the most common system, pulse-code modulation), and for each PCM signal, there is precisely one analog signal corresponding to it that has frequency components below half the sample rate, by the Nyquist–Shannon sampling theorem; that is, if you band-limit an audio sample to some level above the limit of human hearing (a bit below 20kHz) and sample at twice that rate (as with CD audio, at 44.1kHz, is like this) and then convert back to analog, you will get that same band-limited signal.

Now there is some error provided by the discrete volume steps, known as quantization error, but this too can be made imperceptible by means of a high-enough bit-depth (16 bits is fine, maybe 14 bits would have worked, the original proposal for CDs) and a suitable dither (so that the frequency components introduced by quantization error are more uniformly spread out, providing a "noise floor" in which no component is perceptibly loud).

dude, that was awesome, what an incredible explanation, it was very clear and easy to understand for a beginner like me, thank you <3

[captainkeyboard]

This subject pertains to me because I relish computer technology and depend on the computer a lot. It is nice of you to post Digital versus Analog. Your narration was very nice. I enjoy it very much.

[ArtificialIntelligenceQuotent]

Watched a lot of videos but this one is the Best explanation by far.
