Learn more about the process behind analog-to-digital conversion and the important specifications and criteria to consider when selecting and designing with an ADC.
Note that, the fig at 12:00 is not valid anymore. Search for the newer version of it. Nevertheless, flash is fastest and delta-sigma has the best resolution but, stuff in the middle changes over the time.
Amazing Explanation...Just a query..Can I say, if I use an ADC for Raspberry Pi then, (Sampling rate of ADC from manual)>(4*Highest Frequency in my measured signal)
Correction ... we don't live in an analogue world, we live in an digital world because in Quantum Mechanics the smallest possible length is Plank's length, which is a discrete value. Not that it matters.
