scripts default iconQuick spectral analysis plots (Scripts) Publisher's description

The spectra are smoothed by averaging over windows 1/K times the full length of data

data - the data for spectral analysis
K - averaging parameter, explained below
beta - beta value for the Kaiser window
out_form - spectral analysis option
samp_freq - data sampling frequency

out - calculated spectral estimate in form specified by out_form

Averaging Parameter:
The spectra are smoothed by averaging over windows 1/K times the full
length of data. This smoothing method is based upon a technique described
in section 13.4 of "Numerical Recipies in C++", Second Edition.


Each of the above windows are multiplied with a Kaiser window with the
provided window beta value given by the beta input parameter.

Output Format Options:
'as' - amplitude spectrum
'ps' - power spectrum
'asd' - amplitude spectral density
'psd' - power spectral density
'rms' - integrated rms motion

System Requirements:

ATLAB 7.5 (R2007b)
Program Release Status: Major Update
Program Install Support: Install and Uninstall
