Various Representations In the Time-Frequency Plane (for the same signal)
Cohen Class Time-Frequency Distribution
Wigner-Ville Time-Frequency Distribution
Wigner-Ville Time-Frequency Dist. (Half y-axis)
Continuous Wavelet Transform (CWT)
CHsignals.mp4

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').
WIGsignalsFULL.mp4

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').
WIGsignalsHALF.mp4

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').
CWTsig.mp4

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 wavelet used is a Sombrero. (23').
