Time-frequency dependent transformations and their application in digital signal processing Slobodan Simić Bojan Zrnić This paper presents an approach to the non-stationary
signal and process analysis based on time-frequency dependent transformations.
The focus is placed on the Wigner distribution, its time and frequency smoothed
versions and the short-time Fourier transform the results of comparison of the
aforementioned distributions concerning the resolution, interferences, pushing
of the side lobes and characteristics are also presented.
