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.
