Analog-to-Digital Conversion
An ADC measures an analog voltage at a fixed sample rate and quantizes each measurement to one of 2^b levels, so a digital signal is discrete in both time and amplitude; sample rate bounds representable bandwidth while bit depth bounds dynamic range.
This Concept is waiting for its first lesson!
