In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled. It also often refers to the distortion or artifact that results when a signal reconstructed from samples is different from the original … See more When a digital image is viewed, a reconstruction is performed by a display or printer device, and by the eyes and the brain. If the image data is processed in some way during sampling or reconstruction, the … See more Sometimes aliasing is used intentionally on signals with no low-frequency content, called bandpass signals. Undersampling, which creates low-frequency aliases, can produce the same … See more Historically the term aliasing evolved from radio engineering because of the action of superheterodyne receivers.

Websampling and aliasing. Aliasing may appear in many different processes and in different forms, since real proc esses are observed or measured as diverse and complex signals with real instruments that have rather complex properties, and known and unknown shortcomings, related to the task they are supposed to accomplish. WebJan 1, 2024 · Aliasing is a common undesirable phenomenon that occurs wherever digital signals are undergoing processing. You may notice it in audio signals or images. Here is a nifty video that demonstrates aliasing in a music signal. Aliasing can also be found in digital image processing and video processing.

WebAliasing is a signal processing term. Aliasing occurs when a system is measured at an insufficient sampling rate. It is perhaps best explained through example. Imagine a disk (or paper plate) with a dot near the edge. If the disk began rotating at one revolution per minute, you could observe the angular velocity by looking at it.
