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 ...

This HEXUS.help guide explains multi- and super-sampling anti-aliasing. This HEXUS.help guide will assume you know the affects of applying a level of anti-aliasing (AA) on your 3D accelerator, be it ...

If you've ever played a video game on your PC, you've probably seen a setting called "anti-aliasing", which smooths out jagged graphics. But there are different types of anti-aliasing, and some are ...
