Yup...it's very difficult to truly replicate an analog wave form digitally so it's great to see analog kit still being appreciated. Thanks for the post.
Two thumbs up....your video is very helpful to all electronics enthusiast of the world...young and old......Sad that i only toppled on this just now....Hope you'll keep them coming.... Thanks
its interesting that there has been an analog Renaissance last few years - in the states, even some big box department stores are starting to sell record players again - along with recent vinyl reissues of vinyl. And many analog synthesizers now fetch a king's ransom.
yes, you can. You have to attach and detach the interrupt according to the desired pin mode at any given time. The desired pin mode can be stored in a global variable. Read about sleep and wake functions.
Yet again another quality tutorial. Thanks Martin. EDIT: Got stuck a little bit on the binary explanation but I figured it out eventually. Now I just feel stupid for not understanding it instantly.
Thank you so much for these videos, I had no idea that you were going to go into these types of topics and this is exactly why I got into electronics (music).
Nicely explained. When you discussed about the telegraph/Morse, my mind immediately wondered at The Secret Life Of Machines, a series of short documentaries about how technology evolved and was perfected, made by Tim Hunkin. If anyone wants to learn more, the series is excellent and is available for free here on TH-cam (search for the title) and it really explains nicely how telephones, fax machines, word processors (from typing machines to computers), computers etc how all these were made.
Stop the tape. Just wanted to say, I took a computer class in 1969 It took them 4 weeks to describe what you just did in about 3 minutes, and I still did not get it. I dropped out because of the math. I was just sitting here watching this and had a full gestalt, where it all came rushing in and now it makes sense like it never did all those years ago. :o) Just wanted to say thanks.
+BirdWhisperer46 This is very nice and informative video naturally I like it. Something I also found helpfull for introduction to electronics design was Elumpa Circuits Expert Alchemist - if anyone wants to know more search on google
There are several factors in learning electronics. One plan I discovered which succeeds in merging these is the Gregs Electro Blog (check it out on google) without a doubt the most incredible info that I've heard of. Check out this super website.
Hey, I worked for the Telephone Co. for 13 yrs. For plain old telephone service. Break over voltage for ring, 110v. For when the phone is on the hook, 48-54v. When speaking, carrier voltage 10-5v. High speed T1 (4 wire circuits) are kept at 110v. Then the digit is sent +- 5v. That is in America, I don't know what happens in other countries.
Hi Martin, thx you very much for the talk about analog and digital electronics. I like to point out a "very" minor inaccuracy of your wave graph you use as example for explaining quantisation aso. The example might be a bit too theoretically since the wave is going back in time. In practise, I have not seen that much. You know what I mean. ;-)
You forgot to point out on that Agilent meter the bar graph under the digits, which replicates the analogue meter, making it easy to estimate the value just like on that old analogue meter. But it's probably better this way, as not all meters have that graph at the bottom and some can be really slow at updating that, making it almost pointless.
Great video, I'm a mechcanical person where electronics has been a headache, but you explain with such simplicity that I will be following your next videos. Is there any good reading material that you recommend to expand the topics that you are visually sharing? Will you have a class on how to read and follow schematics? Thanks, Oscar A.
it is funny you mention using computers for artillery fire because i was in the army and i was FDC (Fire Direction Control) and we used computers to map out the enemy;s location so the artillery could fire at them
Is it true that your bit resolution can limit the number of opportunities you have to capture a sample of a sound wave?Can you only sample as many times as your bit resolution allows? EX: 8 bit system only allows for a maximum of 256 samples of the sound wave?
yep its kinda working now. i was thrown for a bit but then I broke down some mixed statements into declarations of change and the associated named float or integer then moved the floats and integers to the top and the change statements to the functions below. do you perhaps know if I can reuse the interrupt pin 2 if im using it for sleep? i kinda hoped i could use it as input again but after the rising edge if 5v is present then device stay on. thanks
why when i change my arduino sketch from a sequential void loop to separate functions listed neatly before and called in void loop do my sensors all read 0.00v? i had to duplicate some int lines too as I had some scope warnings before i did. does anyone have an idea? kind thanks
Great videos! Kind of off-topic question when it comes to this video series but doesn't that mean that, in theory, vinyl has a better sound quality than CD (or any digital release)? Assuming that a vinyl record is in a perfect condition and a record player has a perfect needle etc etc. EDIT: Digital release converted from analog release of course... Well, I kind of answered my own question there :D If taking into account all kind of "re-mastering" techniques that exists today answer might vary... But then again, what is quality? Too much questions in my head right now :)
So is it possible to represent a high decimal with a 4 bit binary numbering system? I noticed if there were a 1 in all five bit sections (2^0, 2^1, 2^2, 2^3, 2^4) it could only add up to a total of 31. So can you represent something >=32 with only 4 bits? If so how?
Hi Martin, I recently started watching your videos and I must admit...they're awesome. I find them very educational. But in the tutorial 'basic electronics' you mentioned lessons about transistors and fets. Don't they exist or are they removed? I can't find them. I've watched the others, diodes and capacitors etc...and they were so good that I miss the next ones. Greetz from Belgium and keep up the good work. Thx.
Are you sure you're passing the variables from one function to the other properly? The easiest (but not typically correct) way to do this is to declare all the variables that are used by more than one function, as global variables. Read about "variable scope".
Sorry, I don't think digital maintains the integrity of audio.... It's like taking a renascence painting with perspective and transforming in a perspectiveless medieval picture. One loses information when making digital.But that is just me being annoying musician who still loves vinyl.... And I do understand what means not to care 20 pounds of musical material around. Thanks a lot for your videos! They have been very helpful. :)
in some small way, digital reminds me of the stereotype of a deal with the devil - he gives you the world but takes a piece of your soul in the process
Hey man great information, the editing on your video could be a bit better, got a tad annoying when you where mid sentence then faded to another section of video! Thanks for spending the time to educate us though :)

This video has been rediscovered after many years. Hello there
Thanks very much for the feedback and the correction. I've added an annotation.
awesome tutorial. Always wondered how ADC was done.So glad ive still got lots of tutorials to still go at.
Great tutorial!
Especially the convertion from analog to digital and back...
My pleasure, thanks for the feedback.
The best electronice tutorials so far were the ones you gave!!!!!!!
Thanks for it all
My pleasure, thanks for the feedback. Those power plugs are South African...but I'm based in the US now.

Good explanation of digital audio parameters and bits in general, thanks.

Thanks very much. İ enjoy all tutorials as beginner, but this one also includes history and was interesting
My pleasure.
i really do like and appreciate these tutorials!!!!!! Thank you!!!!!!
Superb video. Will be watching the whole series of vids and will hopefully attempt some practical stuff myself.
I "forgot" on purpose for all the other reasons you mention. Cheers, Martin.
I had an EX 150. it was probably a bit too plug-and-play to teach me enough, hence me following this excellent series.
Thanks..it's a Kodak Prontor 500 LK...there's one eBay for EUR 95...

Hey, really good explanation! Why did you stop making this series?
I really enjoy all your tutorials. Thanks so much!
Indeed...perhaps we can...
Thanks a lot for these tutorials, u got hooked me up to electronics
your explanations are very well presented
Coming soon...
Thanks so much for your videos. I am learning so much more.
Very good video, keep it up! Can't wait for more on this series!

seeing that CD brought back some memories.
I just want to take that stuff apart and play with it!

Thanks
Thanks.
excellent explanation.. hope u continue with more and more videos. total fun !!!

Thank you. You are a great teacher.
those glasses in the beginning are epic
With sunglasses like that I think you spent to much time on Sea Point Promenade! lol….thanks for the tutorials really amazing
great great video Martin! very informative.
One of my favourites! ;-)
hello your videos are great, learned a lot! Thank you so much. Can I download them to watch on the road? best regards
Thank you very much for your tutorials.
Very good videos! Thanks. What country are you based in? Your wall power plugs are something I have never seen.

You definitely know how to teach...Thank you
could you explain about vaccume tubes in audio amp
it is funny you mention using computers for artillery fire because i was in the army and i was FDC (Fire Direction Control) and we used computers to map out the enemy;s location so the artillery could fire at them
Great Video!
What's the name of that mini reel-to-reel?

Omg u have so many kool stuffs haha. Which camera is that? How much does it cost if u cud still buy it:) great video as always.
Thank you!
Great video, Thanks alot
Really nice video :)
But just to remind you that your sound wave graph was going back in time lol
Greetings, Martin! Great video - informative in content and positive overall)
p.s. what happend to the introductory music?
So is it possible to represent a high decimal with a 4 bit binary numbering system? I noticed if there were a 1 in all five bit sections (2^0, 2^1, 2^2, 2^3, 2^4) it could only add up to a total of 31. So can you represent something >=32 with only 4 bits? If so how?
Well we can represent with 4 "bits" 400 numbers, nothing awesome

100% good stuff.
thank you ,good video.
Actually, it was the Philips company that invented both the compact cassette and the CD.
thank you ...
