wigner(1)

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.
