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.
