wigner(1)                      Scilab Function                      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.
