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

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

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.

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!

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).

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

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

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

This is the clearest explanation I have seen given before

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.

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

I like this explanation of the two, well done!

OMG I've been watching videos lately talking about analog computers taking over, they didn't explain the difference so I searched and found your amazing explanation! 😊

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

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

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

From someone fascinated with computers and electronics for most of my life this is a brilliantly informative video and very well explained. Thanks!

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

You always make it so simple. TY

Loved the video, a great analogy! Helps me with classes, and I just love learning this stuff. Thanks, man!!

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

why does this have only 2.7K likes. This guy clearly cares about teaching and put a lot of focus into making these complicated concepts clear for beginners. I have never seen so much information be made so clear with these great analogies. More please!!!

Bro,thanks a bunch.This video really elucidates everything that's in my vague lecture notes 🙏😂

This is a great explanation. Thanks!

You, Sir, have elucidated every point so precisely and depicted it in the most splendid, joyful way that I couldn't have learned anywhere. Thank you for making the sense instead of flinging the graphs!

This is tremendously helpful, thank you so much

very informative, thank you for sharing your knowledge

He's back with a bang!

The explanation is on point!!!!! Very specific just like digital! hahhaha thank u for this!!!

This video is just brilliant, thanks a lot!

Great Video Sir, My Respect to your clear explanation

This video is the excellent. You deserve more view and subscribe.

Thanks!

Fantastic video as always

You are very underrated! SUBBED

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.

Incredible videos you have here! I love how you explain these things so simply! So digital is basically a representation and/or abstract version of analog? That's neat!

Great Video!

I'm an electrical engineering student finding out my passion was in computer and electronics and I found it late, I'm already 4th year student. Now I'm bingeing some of videos about computers and electronics here at KZfaq university.

Excellent video. I wish that my teachers in school could've taught us like this. 😅

i was waiting now got it thanks

really great explained

Love love your content

Nice explain, thank you so much

I finally understood the concept hands down the best explanation

Analog records do not have infinite resolution. There in a limit in the dynamic range and a limit in the frequency range and these can be converted to numbers.

If I get a DAC, will the NORMAL KZfaq music etc. that we get be converted to a superior kind of quality Music? If I install the DAC in between the TV and Home Theatre?

Wonderful Thank you.

Excellent….could you please explain scan lines in analogue camera…I mean what is meant by resolution when using 1980s analog cameras….why do they use that chart to determine resolution…

very nice explanation

Excellent again :)

If dolby atmos creates a realistic representation of sound, is raytracing kind of the same thing with light? sorry this is a very weird question.

you deserve more views

My 12yo students wanted me to comment “good banger video, man”. I think they liked it.

Thank you.

So, help me understand, essentially the difference is about the method of information/data/signal capture and output?

Thanks for your explanation.. As for me i like analogue watches lather digital..

super interesting!

Thank you very helpful

Worth a follow

Very good 👍

Thanks sir!

I'm going to put in extra light switches in each room now. Thanks!

great vid

you are amazing in this video

Thank you for the vid, my brain enjoy ur videos xD

the gradient comparison is soooo good! Learnt a lot! Thank you!!!

Thank you

Loved your explanation. Thank you!

is it possible to make a hybrid digital+analog machine? where you basically only get the pros from both?

Great👍

So, conceptually there’s a difference between analog and digital; but in practice, to an extreme degree, analog is the same as digital just with the Planck units being the de facto switches? And if so, would that mean analog is simply seen as a unary numeral system (base 1)? I’m way out of my depth here - I don’t even know if I’m asking a good question or if I’m just overthinking 😂

Thanks sir

we found it helpful. from HAWI

I'm happy that I watched this video

Of course, on this video the gradients are all digital, but that's still a good representation of "analog" for the analogy.

I must say this even made like my Analog Minolta camera x300 even more

Literally perfect video great editing too Thank you

Pls more videos

Now explain practical limits. A 24 bit signal has more detail then a record could. A detail for example that a vinyl record cant physicslly hold more then what a 14 bit signal could. Or a 35mm film is approximately a 4k-8k image. Even analog has limitlations.

I would understand life so much more clearly if this guy explained everything! Great video :)

Thankអរគុណ

Analogue isn't necessarily better than Digital though, since Analogue devices or Analogue media often tend to be just singular specifically designed pieces of media or information, a picture is just a picture, a picture camera can only do pictures and not motion pictures an analog book is just a book and a VHS tapes can only store videos and not music..... While digital devices can combine all of these and allow you much more than just that through a single device, since the binary code may be used to encode multiple formats of media and view them through a single device, I can both play this video and type this comment and share it online something I wouldn't be able to do on analogue device.

I understood the concept so well. Your practical use cases were just so real.Thanks a lot

While all information in the video is correct. I have to point out that the way it was presented, may lead people into bad conclusions. If you saw this video please do not take away from it the idea that analog is "more precise" or "better" than digital. It is not. both are equivalent to each other and both are suseptible to measurement error during recording and reproduction alike. your eyes and ears also are imperfect when it comes to decoding visual or audio signals so as long as measurement errors for Digital or Analog methods are under the error of your own squshy bits then it will be impossible for you to find difference between them.

Take, for example, a linear 100mm potentiometer with a perfect graphene contact surface. The structure of graphene repeats itself every 213nm (nano meter), shifted. Thats is smooth AF. on a 100mm long potentiometer this gives roughly 46948 discrete contact values. 16 transistors can represent 65536 discrete values. So ... yeah .. thats a thing. The signal delivery of a low quality DAC is more precise than the fanciest linear potentiometer never constructed. There are 64bit digital controllers out there, btw. Thats a 39291863495km long graphene potentiometer.... If my math is correct. Material used for potentiometers are much rougher, with a much higher grain-size than perfect graphene. Conversely, dynamic imperfections, wear and multiple energy states of electrons do have a multiplicative effect on the number of possible values that it can actually deliver. Further, if the grain-size of the pickup is any different than the contact surface, that is a couple of free multipliers provided the two grain sizes are not in a harmonic relationship. Industrial controllers, DACs and other digital control systems are mainly digital because they can revert to an exact state every single time reliably. Pots, ... well, some smaller ones, for example, are just simply incapable of controlling even something as large as a 1/2000 division. One can build a high precision control circuit using analog only, true. Time domain sensitive and feedback systems have these. Hell, arrange a couple of pots in parallel and you are halfway there. Some lab equipment I used back in uni had this. But for storage and post processing, for example, analog systems make no sense. Data is capable to represent a precision level which would equal to half a muon on an LP (i should do this calculation too). Information potentially exposed by analog systems is indeed close to infinite. Unusable, random information, that is. This "Random information" is still regularly emulated digitally in the music industry. Digital can be imperfect, analog can never be perfect. The Heisenberg uncertainty principle explains that quite clearly. Eventually this chaotic nature of the very small gives the illusion of ... infinite. But it is not. In fact it is quite coarse. Electricity does have a quanta. You can never subdivide that. To something abstract as a digital data point, you just add a bit. The last part was almost inspired. Digital data is an abstract representation. One of the quirks of abstracts is that their lower level can be scaled indefinitely .... we are conceptually comparing apples and elephants. But, I digress. "The greatest shortcoming of the human race is our inability to understand the exponential function"

So insightful

wow! Thanks. Very clear explanations.

How does this vid only have 11k views? Great video and presentation!

Still not sure I get why analog signals are so thoroughly associated with lower quality media, particularly visuals (although I guess I've heard people say records have a "warmer" sound and film grain is "richer" than digital). Is the reliability and repeatability paradoxically what makes it possible for digital video to look so much better than analog even though analog is technically "realer" in how continuous and physical it is? Like it would be much harder mechanically and more expensive to make an analog tv that has the crispness and definition of a digital one simply because all that complexity can be neatly "folded up" into binary bits hence you can have smaller screens and devices delivering higher resolution information in cheaper form factors compared to analog? Is the "fuzz" associated with analog tvs and radios actually a consequence of being a continuous physical signal? I'm old enough to remember turning dials on radios and if you went just a little to far the signal would get unintelligible.

great

Analog signals are those can have anything continues but digital signals can have only 01 in discreet wave

Worth noting that the accuracy claims are a bit overstaded because analog process are extremely vulnerable to noise and biases while digital is extremely resilient. Like sure a record might store an nearly infinitely precise signal but it doesn't mean it is accurate to the source sound.

nice

I wonder how qbits will play into this.

How is it 2switch 50 2 50

👍👍👍

Thank you. Very helpful
