Aliasing definition. Aliasing is the effect of overlapping frequency components resulting from unsufficiently large sample rate. In other words, it causes appearance of frequencies in the amplitude-frequency spectrum, that are not in the original signal.
In signal processing and related disciplines, aliasing is the overlapping of frequency components resulting from a sample rate below the Nyquist rate. This overlap results in distortion or artifacts when the signal is reconstructed from samples which causes the reconstructed signal to differ from the original continuous signal.
Mar 21, 2024 · The aliasing effect, also known as aliasing distortion or simply aliasing, is a phenomenon that occurs in signal processing, particularly in digital signal processing (DSP), when a continuous signal is sampled at a frequency that is too low to accurately represent the original signal.
ALIASING definition: 1. the use of aliases (= different names) to find computer files, commands, addresses, etc. 2. the…. Learn more.
Apr 19, 2012 · What Does Aliasing Mean? Aliasing is an effect that causes different signals to become indistinguishable from each other during sampling. Aliasing is characterized by the altering of output compared to the original signal because resampling or interpolation resulted in a lower resolution in images, a slower frame rate in terms of video or a ...
Jun 17, 2020 · In fact, aliasing is the phenomenon in which a high frequency component in the frequency-spectrum of the signal takes identity of a lower-frequency component in the spectrum of the sampled signal.
May 22, 2022 · Aliasing occurs when each period of the spectrum of the samples does not have the same form as the spectrum of the original signal. Given a continuous time signals \ (x\) with continuous time Fourier transform \ (X\), recall that the spectrum \ (X_s\) of sampled signal \ (x_s\) with sampling period \ (T_s\) is given by.
Oct 14, 2022 · Aliasing refers to a scenario when two or more variables refer to the same value in memory. As a result, aliasing can only occur—to my knowledge—in programming languages that support references. References, for the uninitiated, are variables that store the location of some data.

Jun 25, 2022 · In computer graphics (as well as other disciplines), antialiasing refers to a collection of techniques to reduce the effects of aliasing. When a continuous signal or image is sampled, or a digital image is resampled, the sampling imposes a limit on the frequencies available in the input signal that can be represented in the resulting output signal.
