Understanding Analog to Digital Conversion

Using Analog to Digital Converters (ADC) is a common practice, but understanding what type of ADC is being used is not common.

Bil Herd scratches the surface of ADCs, delving into Flash, SAR and Dual-Slope conversions. He shows the underlying designs of each, discussing how they work and how they fit into the sample rate/resolution/cost equation.

All Bill videos should get automatic free promotion! Just get back to this video after 5y and still found it amazing!

[BilHerd]

Thanks guys. Always open to suggestions to improve!

Such a good explanation..! And the graphical illustration with actual parts as well is just create!
One thing only, is that @13:05 you show 2 different input voltages but they both have the same first slope and different time at which they switch, but it's actually exactly the opposite, same time different slope.

Man this is a bloody great video! You do an incredible job of getting the information across in a way that really works for me. Thank you!

Great video! the demo with the fpga was very interesting.

Woooow, this is just to great to have only 5k views. Thanks a lot for this!

Finally a tutorial that provides real demonstration, though the video lost me at 15:04 when it started to explain how the discharge time is count. Which count represents the discharge time - is it the Count-In, I/O Port, or the Counter? The figure drawn is confusing - it starts counting the Count-In, then terminate, then follows with counting on the IO, and finally there's a blue-pulse that gets triggered? That doesn't make much sense.

Great job and lol to 1024 word! Very useful video. Thanks for putting all effort

"Picture worth more than 1024 words" xD Great video!

I am excited that I found your channel. I am a Surveillance Technologies Technician in the casino business. It is the perfect tranquil world of analog and network convergence. I may email you or post in your forums, but in the mean time, I am quickly going through a stock of used proprietary encoders. NVE1008. The company was called NICE before they discontinued the product and changed their name to Qognify. It happens, I know. I'd like to build my own. Ideas? I have one disassembled.

What about a saw tooth wave and 8 bit register syncronised off the same clock and cycling between their minimum and maximum values and running that saw tooth wave and analog circuit through a comparator to latch the data in the register? Am I going to find out that's what a delta sigma does?

I wished I had a lab like this one omg

8 bit ADC shouldn't mean 256 comparators; it should mean 256 values per sample and hold conversion.
