aliasing
This term is primarily used in technical contexts such as digital signal processing, audio engineering, and computer graphics. It describes a specific type of artifact or error where a signal is incorrectly reconstructed, leading to a perceived distortion that was not present in the original source.
In visual contexts, it is often referred to as "jaggies," describing the stair-step effect on diagonal lines. Because it is a technical process or phenomenon, it is treated as an uncountable noun; one does not refer to "multiple aliasing" but rather to "the presence of aliasing" or "aliasing artifacts."
Meanings
The effect of distortion that occurs when a continuous signal is sampled at an insufficient rate, causing high-frequency components to be misrepresented as lower frequencies.
Examples
The low resolution of the old monitor caused noticeable aliasing on the diagonal lines.
The low resolution of the old monitor caused noticeable aliasing on the diagonal lines.
I can see some aliasing around the edges of the building in this screenshot.
We need to apply a low pass filter to prevent aliasing during the sampling process.
The audio sounds metallic because of aliasing in the digital conversion.
Aliasing occurs when the sampling frequency is less than twice the highest frequency component.
The jagged edges are a classic example of aliasing in early 3D games.
I wonder if increasing the sample rate will eliminate this aliasing effect.
