Aliasing (computing) - Wikipedia

WebIn computing, aliasingdescribes a situation in which a data location in memorycan be accessed through different symbolic names in the program. Thus, modifying the data through one name implicitly modifies the values associated with all aliased names, which may not be expected by the programmer. 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 continuous signal. Aliasing that occurs in signals sampled in time, for instance in digital audio or the stroboscopic … WebAliasing definition: Visible or audible distortion introduced into digital information, such as images or audio signals, caused when a continuous line or transition is not smoothly captured or represented because of the low resolution or sampling rate of a digital medium. criminal background check scotland

WebJan 1, 2024 · What is aliasing? Aliasing is an unwanted case of sampling, where the minimum condition for accurate sampling is not met. Thus there is an overlap in the shifted replicas of the x (ω) signal. Consequently, the x (t) signal can neither be sampled accurately or recovered from its samples.
