SPSD implements the smoothed (binned) PSD algorithm for analysis objects. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: SPSD implements the smoothed PSD algorithm for analysis objects. CALL: bs = spsd(a1,a2,a3,...,pl) bs = spsd(as,pl) bs = as.spsd(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 |
| WIN | 'Hanning' |
|
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 either:
|
| PSLL | 200 | none | the peak sidelobe level for Kaiser windows. Note: it is ignored for all other windows |
| LEVELORDER | 2 | none | the contracting order for levelledHanning window |
| ORDER | 0 |
|
order of segment detrending:
|
| TIMES | [] | none | time range. If not empty, sets the restricted interval to analyze |
| SCALE | 'PSD' |
|
scaling of output. Choose from:
|
| LINCOEF | 1 | none | Linear scale smoothing coefficent (freq. bins) |
| LOGCOEF | 0.66666666666666663 | none | Logarithmic scale smoothing coefficent Best compromise for both axes is 2/3 |
