Aliasing can occur in signals sampled in time, for instance in digital audio or the stroboscopic effect, and is referred to as temporal aliasing. Aliasing in spatially sampled signals (e.g., moiré patterns in digital …

Jul 23, 2025 · 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 …

Information is generally lost in such discretization processes. Today we discussed two mechanisms that can alter the information con-tained in a signal: aliasing and quantization. Next time, we will develop …

Aliasing, essentially the signal processing version of identity theft, occurs when each period of the spectrum of the samples does not have the same form as the spectrum of the original signal.

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 …

Jun 14, 2025 · Explore the concept of aliasing, its implications on digital signal processing, and practical strategies for managing aliasing in various applications.

What is aliasing? Aliasing is the name we give to the phenomenon when two distinct continuous signals x 1 (t) and x 2 (t) produce the same sequence of sample values x [n] when sampled at a fixed rate f s.

Aliasing Explained In signal processing and related disciplines, aliasing is a phenomenon that a reconstructed signal from samples of the original signal contains low frequency components that are …

Anti-aliasing includes several techniques in computer graphics and computer-generated imagery to combat the problems of aliasing in a sampled signal such as a digital image or digital audio recording.

This article explains the basics of aliasing and introduces the anti-aliasing technique used to combat it. Aliasing is a phenomenon that occurs during analog-to-digital (A/D) conversion due to insufficient …
