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 …

Adjust sample rate and signal frequency in real time and watch aliasing happen before your eyes. Animated Nyquist theorem tutorial with a quiz. Free DSP lesson.

Sampling above Nyquist ) Aliasing to a frequency below Nyquist If you try to sample a signal whose frequency is above Nyquist (like the one shown on the left), then it gets aliased to a frequency below …

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.

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 …
