Time-frequency domain analysis of vibration signals for machinery diagnostics (1) Introduction to the Wigner-Ville distribution

Subtitle:
OUEL Report 1859/90
Abstract:

This report reviews the definition and some of the properties of the Wigner-Ville distribution for both continuous and discrete signals. A digital computer program implementing the discrete Wigner-Ville distribution is described and its performance is demonstrated by the analysis in the time-frequency domain of a series of numerically-generated test signals, showing the form of the Wigner-Ville distribution and the interference terms which can be generated due to its non-linear behaviour. The...
