SpectgAs.mp4: Spectrogram (in the Time-Frequency plane)

of two slighly different Gabor atoms whose internal frequencies

progressively increase. Note that the result depends highly on the

parameter setting but it shows a lower "resolution" compared with

other decomposition types such as Cohen class distribution.

Time-Frequency plane: abscissa=0,...,1, ordinate=0,...,1. (05').
