Abstract
The Wigner Distribution (WD) introduced by Wigner in 1932 as a phase representation in Quantum Mechanics gives a simultaneous representation of a signal in space and spatial frequency variables [1-2]. The WD might be interpreted as a local or regional spatial-frequency representation of a signal. However, it presents two main advantages with respect to other local representations. First, the WD is a real valued function and encodes directly the Fourier phase information. Second, the election of the appropriate window size which depends upon the kind of the analyzed information, is not required for the computation of the WD.
