PSD makes power spectral density estimates of the time-series objects %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: PSD makes power spectral density estimates of the time-series objects in the input analysis objects using the Welch Overlap method. PSD is computed using a modified version of MATLAB's welch (>> help welch). CALL: bs = psd(a1,a2,a3,...,pl) bs = psd(as,pl) bs = as.psd(pl) INPUTS: aN - input analysis objects as - input analysis objects array pl - input parameter list OUTPUTS: bs - array of analysis objects, one for each input Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Key | Default Value | Options | Description |
NFFT | -1 | none | The number of samples in each fft [default: length of input data]. A string value containing the variable 'fs' can also be used, e.g., plist('Nfft', '2*fs') |
WIN | 'BH92' |
|
The window to be applied to the data to remove the discontinuities at edges of segments. [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 |
OLAP | -1 | none | The segment percent overlap [-1 == take from window function] |
ORDER, N | 0 |
|
The order of segment detrending:
|
NAVS | -1 | none | Force number of averages. If set, and if Nfft was set to 0 or -1, the number of points for each window will be calculated to match the request. |
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:
|
SCALE | 'PSD' |
|
The scaling of output. Choose from:
