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. Web(1) See alias .

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. WebAliasing – from alias – is an effect that makes different signals indistinguishable when sampled. It also refers to the difference between a signal reconstructed from samples and the original continuous signal, when the resolution is too low. Basically, aliasing depends on the sampling rate and freqency content of the signal. ross company site stormworx of nc
