In particular, aliasing errors are shown to be phase sensitive and can therefore be controlled by suitable equalization of the relative phase of observed input-output signals.doi:10.1080/00207177508922089P. E. WELLSTEADTaylor & Francis GroupInternational Journal of Control...
In signal processing systems, aliasing is normally treated as a disturbing signal. That motivates the need for effective analog, optical and digital anti-aliasing filters. However, aliasing also conveys valuable information on the signal above the Nyquist frequency. Hence, an effective processing of ...
There might still be a need for an analog prefilter to attenuate components above 5 kHz to prevent aliasing in the input. Fortunately, few digital control systems have problems with aliasing, and often you will be able to ignore the effect. High-frequency signals in analog control systems, ...

An Aliasing Filter is a type of low-pass filter used in digital systems to eliminate unwanted signals above the Nyquist frequency, reducing jagged edges or roughness in digitized images or sound caused by aliasing.

For a fixed sampling rate that isn’t sufficient to capture the function, both uniform and nonuniform sampling produce incorrect reconstructed signals. However, nonuniform sampling tends to turn the regular aliasing artifacts into noise, which is less distracting to the human visual system. In frequ...
Spectral aliasing – moire or herringbone patterns where none should be – appears as a result of interference between digital signals, such as color and brightness. How It Works In graphics or type, anti-aliasing algorithms sample, or examine and evaluate, the colors and shades of pixels adjoin...
