wigner            Scilab Group            Scilab Function            wigner
NAME
   wigner - 'time-frequency' wigner spectrum
  
CALLING SEQUENCE
 [tab]=wigner(x,h,deltat,zp)
PARAMETERS
 tab        : wigner spectrum (lines correspond to the time variable)
            
 x          : analyzed signal
            
 h          : data window
            
 deltat     : analysis time increment (in samples)
            
 zp         : length of FFT's. %pi/zp gives the frequency increment.
            
DESCRIPTION
   function which computes the 'time-frequency' wigner spectrum of a signal.
