Various Representations In the Time-Frequency 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'). |
