Aliasing - Wikipedia
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 …
10.5: Aliasing Phenomena - Engineering LibreTexts
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.
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 Effect - GeeksforGeeks
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 …
Aliasing Definition - Electrical Circuits and Systems II Key Term ...
Aliasing occurs when a continuous signal is sampled at a rate that is insufficient to capture the changes in the signal accurately, resulting in a distortion where different signals become indistinguishable …
The Ultimate Guide to Aliasing in Signal Processing
Jun 11, 2025 · Aliasing is a fundamental concept in signal processing that occurs when a continuous-time signal is sampled at a rate that is insufficient to capture its full frequency content.
2.2. Aliasing — Digital Signals Theory - Brian McFee
Aliasing is an unavoidable consequence of digital sampling: there will always be frequencies that look the same after sampling. The consequence of this fact is that once you’ve sampled a signal, you may …
Aliasing Explained
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 …
What is aliasing? What causes it? How to avoid it? | WolfSound
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 …
Aliasing and Anti-Aliasing Techniques : Key differences - RF Wireless …
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 …
