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.

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

Another great, clearly explained video. Thank you

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

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.

Voavvv very very informative a girl. I would follow you on instagram and learn something from you. Can you let me know your ID ? :))

Ooooooh, 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!

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?

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

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?

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.. 😂

what is the output if vanlog and vref is equal?

Please describe autopilot analog input to digital in flight management computer then into analog into actuator

Holaaaaa, muchas gracias.

Very good

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.

Aside from the ADCs built-in to most modern microcontrollers are there any ubiquitous DIP ADCs to experiment with? Like something as famous /recognizable as a 555 timer or the 7400 logic series?

A few old ADCs, but most modern ADC chips would use an i2c interface. The ADCs built into most microcontrollers are actually pretty rubbish, so it's very common to use an external one on an i2c connection. I built a project using an ADS1115 once - the sample rate is poor, but it can do differential measurements, the resolution is far superior to an atmega, and it has a built-in programmable amplifier that lets you do very precise measurements of tiny voltage differences. I used it to make a curve tracer for measuring the properties of diodes and transistors, as a way to detect the many fake parts you get buying on eBay.

ADC0804, ADC0808 were very popular IC's, back in day's. ADC can be assembled from few hex inverter IC's too. I did it long time ago for one project. 2 cheap IC's, bunch of resistors and 5 bit resolution at the output.. Only, how I remember, I didn't use 74 series but CMOS IC's - CD4049..

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.

Can u suggest a substitute for ak5358 ic

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

Surprisingly easily. Two common ways. 1. Generate a PWM signal using an all-digital counter circuit, then filter this using a simple RC filter circuit (often external) and buffer. This is how arduino and Raspberry Pi audio work. 2. A line of resistors, connected to each bit and values carefully chosen so that each contributes exactly the right amount to the output voltage. More expensive to fabricate, but much higher bandwidth.

Common enough that you can get single-chip solutions that do the whole process from reading the bitstream straight from the laser right to outputting audio ready to feed into an amplifier. Though they are not easily available, as they are usually a custom order for a specific manufacturer.

yes, more then one.

Hi, dear you genius or The God gifted you are doing a whole world students are also professionals get so much information... If you need any help from my side analog and digital and quantum electronic for robots technology... I have 20 years experience but The God gifted.

ADC's work with a good support on botlane, just need to get enough CS and you can carry!

at 3:21 it should be Vref=3.5 volt otherwise you missed a resistance kzread.info/dash/bejne/mWh22MR6e7G3aZM.html

Listening to you in the video only tells me you know your stuff however the art of teaching is how simple you make the information to the listener or reader. If you introduce a new term while explaining a topic you have just added a new topic. The more you add without fully explaining the new topic in simple terms the more confusing your lecture becomes

Why is this junk? There are dimmers for a long time.
