S. Stankovic et L. Stankovic, AN ARCHITECTURE FOR THE REALIZATION OF A SYSTEM FOR TIME-FREQUENCY SIGNAL ANALYSIS, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 44(7), 1997, pp. 600-604
An architecture of the system for time-frequency signal analysis is pr
esented. This system is based on the S-method, whose special cases are
two the most important distributions: the Spectrogram and the Wigner
distribution. Systems with constant and signal-dependent window widths
are presented.
