A signal processing operation, such as sampling a signal or synthesizing a signal having a desired frequency specified by a control signal, is performed in response to the jittered pulses. Setup time aliasing is avoided by alternating between two signal processors, each driven by one of a pair...
Aliasing is an artifact of under-sampling data. It is a term commonly used in signal processing fields. When aliasing occurs in an audio signal, it can be heard as a highpitched whining or crunching sound. You may have noticed this in old video games, musical greeting cards, or children’...
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 ...

A signal-processing model is proposed in which the phenomenon of 'aliasing' is invoked to explain certain phenomena in the perception of musical tones, for which a really satisfactory explanation has not hitherto been available. It is shown that this model offers a reason why the harmonic series...
The aliasing effect is a measurement error in the signal occurring due to an incorrectly set sampling rate. If the sampling rate is too low, the Nyquist-Shannon sampling theorem is not observed and thus the measurement signal is not acquired correctly. ...

The input could then be digitally filtered to attenuate frequency components above 500 Hz before the signal was shuttled to the 1-kHz control laws. There might still be a need for an analog prefilter to attenuate components above 5 kHz to prevent aliasing in the input. Fortunately, few ...
