The I.T Crowd shirt is just beyond awesome lol

Thank you for providing the working principles of multiple ADC types in such a lucid and vivid presentation! . these tutorials help me out a lot.

You're a good & big teacher.
You do & explain always very well.
Nice to you.
Many thanks Teacher & Master.

Very interesting. Thanks, Karen! I will have to re-watch to get all the details.

I love your smile, explicas de manera sencilla y detallada, gracias, abrazo desde México

Maker Karen. Thanks for your generous sharing of knowledge.

First ADC, what I assembled, back in days, was created with opamp, who converted audio input in PWM signal.. Then firmware measured time between each period.

Second ADC I assembled from two CD4049 IC's. First one IC did all job, using resistor feedback network to next element, second one was as buffer for digital output.

Still have next version - AD7581 IC's analog manufactured 1992 in Riga. That ADC working in my DIY stereo system for audio capture from multiple channels for level displaying.. Some time ago, that system has an output for disco lights, using same base data. Removed when previous MCU run out of space. Updated MCU, updated system buses and I didn't put Disco lights output back..

I don't use Arduino, I'm using Atmel MCU's directly, by now, more than 20 years.. 😂

Amazing quality, thanks for your work.

For Flash ADC circuit, there should be 2^N resistors, you show the right voltage drop from 4.0V to 3.5V but without any resistor in between.

Bottom line is there is a lot of information to relate. Perhaps divide into very small sections each covered in simple terms and at a reasonable speed. Obviously there are tons of ways nowadays to digitize an analog signal. Some are more preferred than others but the key here is the listener only needs to know what is analog, what is it for, an example. Then what is digital, why do I want to digitize a signal and why use one method over the others. Keeping focus on using the simplest language. Thanks a million

Another great, clearly explained video. Thank you

[maxk]

lol of course it just eventually converges on being variations of hardware implemented PID control loops with the voltage reading beign the output. Should've thought of that. Thanks for the awesome informative video!

[ajinkyamahajan]

Wonderfully explained 😊
I wish you cover a Video dedicated to Delta Sigma ACD in Future
Thanks.

[extractiongames]

thank u sister really useful may Allah bless u

10:12 why 3.5V in uppermost when the vref is 4V? They are just in the same node so they must have the same voltage.

I wonder about how DAC's works. The next video could be about it.

[goodsound]

So the bits are used for the value and the sample rate for accuracy over time; but how are the frequencies converted? Is there one sample for 20 Hz and then another sample for 21 Hz and so on, to re-create the complexity of the music signal?

[villagerse]

Can u suggest a substitute for ak5358 ic

[sociocyberneering]

Would you say that an airplane ACE (actuator control electronics) works much this way. When a pilot moves a control the analog signal goes to an ACE, then the digital signal goes to a PFC (primary flight control computer) giving an appropriate command in digital back to the ACE. The ACE converts it back to analog to move a control surface.

FYI: This is the fly-by-wire flight control system of a B777.

Hey there! I came across this video in search for more understanding of bit depth. I'm a learning audio engineer and my teacher was telling me that in A/D conversion, more bit depth increases the dynamic range due to less equalization noise being added. However, he said that more bit depth doesn't equal more definition or more available bits to be used in a specific deciBel. It confused me a lot and I'm in need for an answer. Does a bigger bit depth increase definition/ provide more accurate readings of an analog signal in a specific sample?
