"WebSep 4, 2015 · Anti-aliasing filters. Most ADCs are preceded by an anti-aliasing filter, which is nothing more than a low-pass filter used to attenuate signals beyond the bandwidth of interest. The response of an ideal anti-aliasing filter is perfectly flat up until the Nyquist frequency, after which it rolls off sharply to attenuate out-of-band frequencies ... " - Aliasing effetto

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. WebFor specific types of inputs the effect of frequency aliasing on the magnitude of autocorrelations may be negligible. However, I don't think this will be true in general. For instance, for a bandlimited input or for white noise the under-sampling will not impact the shape of the autocorrelation (although it might change the scaling in a ...

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.
