If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

One of the fundamental processes involving digital signals is sampling. When sampling video and audio, the question inevitably comes up as to what is optimum sampling. Just how much resolution do we ...

Every so often someone publishes an article discussing aliasing. I thought I’d jump on the bandwagon – you know, that one in the movies whose wheels seem to be rotating the wrong way. Is aliasing a ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...
