Aliasing. The occurrence of spurious signals in an output signal that were not present in the input signal due to under-sampling [fold-over of the higher frequencies]. The error introduced in a system that is not able to sample a signal at the required frequency. A Digitizing circuit that does not operate to the required incoming frequency producing a completely different frequency at the output.
NYQUIST. A theorem that determines the minimum sampling rate of a signal so that the original frequency is preserved. A Sampling theorem.
Aliasing, Under-Sampling
NYQUIST INTERVAL. The interval in time between minimum sampling times, which is also half the bandwidth of the signal being sampled.
