 WIGsignalsHALF.swf: WignerVille TimeFrequency 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 TimeFrequency plane: [0,1] vs.[0,1/2]. (23') (Adobe Shockwave flash file).
