Method ao/dtfe

  DTFE estimates transfer function between time-series objects.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: DTFE makes discrete transfer function estimates of the time-series
               in the input analysis objects. The estimate is done by taking
               the ratio of the DFTs between the two inputs at the
               specified frequencies.
 
  CALL:        b = dtfe(a1,a2,pl)
 
  INPUTS:      a1   - input analysis object
               a2   - input analysis object
               pl   - input parameter list
 
  OUTPUTS:     b    - output analysis object

[default: taken from user prefs]
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')
PSLL 200 none The peak sidelobe level for Kaiser windows.
Note: it is ignored for all other windows
SCALE 1
  • 1
  • 0
 Scale the output according to the applied window resulting in [unit] rms.
F, FREQUENCIES, F0 -1 none The vector of frequencies at which to compute the DFT
or an AO where the x-axis is taken for the frequency values.
NBINS 5 none The number of bins either side of each frequency from which to compute the mean error.The error will be computed from the bins deltaF*[-Nbins-skip:-skip skip:skip+Nbins] where deltaF = fs/Nsamples is the frequency resolution.
SKIP 3 none The number of bins either side of each frequency to ignore when computing the mean error.

  • 7
  • 8
  • 9
 The order of segment detrending:
  • -1 - no detrending
  • 0 - subtract mean
  • 1 - subtract linear fit
  • N - subtract fit of polynomial, order N
TIMES, SPLIT [] none The time range to analyze. If not empty, sets the time interval to operate on.
As in ao/split, the interval can be specified by:
  • a vector of doubles
  • a timespan object
  • a cell array of time strings
  • a vector of time objects
