Various Representations In the TimeFrequency Plane (for the same signal)  






for a signal that consists of: 1) Two slighly different Gabor atoms whose internal frequencies progressively increase. 2) A dirac, 3) A sinusoid, 4) A noise that increases at each sequence repetition. (23'). 
for a signal that consists of: 1) Two slighly different Gabor atoms whose internal frequencies progressively increase. 2) A dirac, 3) A sinusoid, 4) A noise that increases at each sequence repetition. The calculation (quadratic) interference terms are easily visible. (23').
