dc.description This is the first reported real-life application of time-frequency signal analysis using the Wigner-Ville distribution, and presents the issues related to the application of the method such as cross-terms, condition of positivity, relationship with the IF and others. A software package that calculates IF estimates and TFDs can be downloaded from the web site: www.time-frequency.net en_US
dc.description.abstract The Wigner-Ville joint representation (WVJR) appears as a quite good candidate among the various time and frequency JR. This JR performs exact demodulation of finite energy signals even in presence of linear filtering. Signal or waveform synthesis may be derived from this JR or from ambiguity function. Asymptotic signals are depicted in such a way that modulation parameters may be estimated. Dealing with vibroseismic signals the WVJR allows to identify damping parameters related to propagation effects. Propagation models may be checked by this technique. An example of such a technique is provided by processing of synthetic seismic data. en_US
