Abstract
This paper deals with the time-frequency analysis of deterministic and stochastic non-stationary signals. It includes the following: a brief review of the fundamentals of time-frequency analysis and various time-frequency distributions; a summary of the inter-relations between time-frequency distributions, emphasizing links between evolutionary spectra, the Wigner-Ville distribution, and Cohen-class distribution; demonstration of the effects of using different analysis methods on sample time histories; the analytical modelling of physical phenomena so as to predict theoretical time-frequency distributions, with a view to offering insight into the signal generation mechanisms.
