Key Default Value Options Description
fft
TYPE 'one'
  • 'plain'
  • 'one'
  • 'two'
 The fft type. Choose between:
  • Plain (complete non-symmetric)
  • One-sided (from zero to Nyquist). Please notice that this applies only to tsdata ao with real values in y.
  • Two-sided (complete symmetric).
SCALE 0
  • 0
  • 1
 set to 'true' to scale FFT by sampling rate to match amplitude in continuous domain. Only applicable to time-series AOs.
WIN 'Rectangular'
  • 'Rectangular'
  • 'Welch'
  • 'Bartlett'
  • 'Hanning'
  • 'Hamming'
  • 'Nuttall3'
  • 'Nuttall4'
  • 'Nuttall3a'
  • 'Nuttall3b'
  • 'Nuttall4a'
  • 'Nuttall4b'
  • 'Nuttall4c'
  • 'BH92'
  • 'SFT3F'
  • 'SFT3M'
  • 'FTNI'
  • 'SFT4F'
  • 'SFT5F'
  • 'SFT4M'
  • 'FTHP'
  • 'HFT70'
  • 'FTSRS'
  • 'SFT5M'
  • 'HFT90D'
  • 'HFT95'
  • 'HFT116D'
  • 'HFT144D'
  • 'HFT169D'
  • 'HFT196D'
  • 'HFT223D'
  • 'HFT248D'
  • 'Kaiser'
  • 'levelledHanning'
 The window to be applied to the data to remove the discontinuities at edges of segments. [default: rectangular one]
Only the design parameters of the window object are used. Enter a string value containing the window name e.g.
plist('Win', 'Kaiser', 'psll', 200)
plist('Win', 'BH92')

Example
plist('TYPE', 'one', 'SCALE', [false], 'WIN', 'Rectangular')
