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 ...

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 ...

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 ...
