Time-frequency domain analysis of vibration signals for machinery diagnostics (II) The weighted Wigner-Ville distribution

Subtitle:
OUEL Report 1891/91
Abstract:

This report examines the application of sliding weighting functions to the Wigner-Ville distribution. The effect of the weighing function on the time-frequency distribution is discussed and it is shown that the level of the interference terms, the production of aliasing errors and the repetition terms in the weighted Wigner-Ville distribution are significantly reduced. It is suggested that the Gaussian function provides a suitable form of weighting function. A digital computer program impleme...
