Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

In An Approximation to the Aliasing Effect, Part 1: The Origin I revisited some basic concepts about the aliasing effect, though I did it from a more visual than theoretical perspective. This second ...

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 ...

With the growing use of multiple video formats, a fundamental understanding of sampling rate conversion will provide insight into the quality and operation of format converters. However, before ...

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

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 played a PC game in the past five years, you’ve probably stumbled across an anti-aliasing toggle while mucking about with your graphics settings. Switching it on can make everything on your ...
