In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.
In computing, aliasing describes a situation in which a data location in memory can be accessed through different symbolic names in the program.
An example of aliasing can be seen in old movies, ... These false frequencies will appear as mirror images of the original frequency around the Nyquist frequency.
1. When several different identifiers refer to the same object. The term is very general and is used in many contexts. See alias, aliasing bug, anti-aliasing.
It’s easiest to describe aliasing in terms of a visual sampling system we all know and love—movies. If you’ve ever watched a western and seen the wheel of a ...

In digital signal processing, anti-aliasing is the technique of minimizing aliasing (jagged or blocky patterns) when representing a high-resolution signal at a lower ...
In sound and image generation, aliasing is the generation of a false (alias) frequency along with the correct one when doing frequency sampling.
