dc.description This paper discusses the issue of aliasing in the bispectrum computation. (The most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia, and then continuously updated). en_US
dc.description.abstract Digital signal processing of continuous signals requires sampling of the continuous signal. When sampling continuous signals it is important to avoid the effect called aliasing. Aliasing causes signals at particular frequencies to appear, erroneously, as signals of different frequencies. Consequently, it is important that before any digital signal processing is performed, the sampled signal is known to be free of aliasing. A published test based on the bispectrum purports to be able to detect aliasing of an already sampled signal. The authors provide counter examples to demonstrate that this previously published test for aliasing is not valid in practice. en_US
