WGatoms.swf: Wigner-Ville Time-Frequency Distribution (in the Time-Frequency plane) of two slighly different Gabor atoms whose internal frequencies progressively increase. Time-Frequency plane: [0,1] vs [0,1]. Observe the calculation interference (quadratic) terms (06').


WGatomsHALF.swf: Same as above but for a Time-Frequency plane such that [0,1] vs [0,1/2]. Observe the calculation interference terms. (06').


ChGatoms.swf: Cohen class Time-Frequency Distribution (in the Time-Frequency plane) of two slighly different Gabor atoms whose internal frequencies progressively increase.(06').


WIGsignalsFULL.swf: Wigner-Ville Time-Frequency Distribution of a signal that consists of: (1) two slighly different Gabor atoms whose internal frequencies progressively increase, (2) a Dirac, (3) a sinusoid, (4) and a noise that increases at each sequence repetition. Observe the calculation interference terms. In the Time-Frequency plane: [0,1] vs.[0,1]. (23').
