aliasing
1. <jargon> 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.
2. (Or "shadowing") Where a hardware device responds at multiple addresses because it only decodes a subset of the address lines, so different values on the other lines are ignored.

Aliasing
The “jaggies,” those stair-stepping patterns that occur on a diagonal or curved line on a computer or video display. Can be smoothed or corrected through anti-aliasing processes.

Aliasing
(1) In computer graphics, the process by which smooth curves and other lines become jagged because the resolution of the graphics device or file is not high enough to represent a smooth curve. Smoothing ant antialiasing techniques can reduce the effect of aliasing.
(2) In digital sound, aliasing is a static distortion resulting from a low sampling rate–below 40 kilohertz (Khz).

Anti-Aliasing
Removing the ugly "stair-stepping" or "jagged" effect that degrades the sharpness of polygons. Usually caused by low resolution.

Aliasing
Aliasing is the term used to describe the unwanted frequencies which are produced when a sound is sampled at a rate which is less than twice the frequency of the highest frequency component in the sound.

Aliasing
An effect caused by sampling an image (or signal) at too low a rate. It makes rapid change (high texture) areas of an image appear as a slow change in the sample image. Once aliasing occurs, there is no way to accurately reproduce the original image from the sampled image.

aliasing
Undesired frequencies that are produced when harmonic components within the audio signal being sampled by a digital recording device or generated within a digital sound source lie above the Nyquist frequency. Aliasing differs from some other types of noise in that its pitch changes radically when the pitch of the intended sound changes. See Nyquist frequency.

Aliasing
- This article applies to signal processing, including computer graphics. For uses in computer programming, please refer to aliasing (computing).
In statistics, signal processing, computer graphics and related disciplines, aliasing refers to an effect that causes different continuous signals to become indistinguishable (or aliases of one another) when sampled. It also refers to the distortion or artifact that results when a signal is sampled and reconstructed as an alias of the original signal.
