The integral of the PSD over a given frequency band computes the average power in the signal over that frequency band. In contrast to the mean-squared spectrum, the peaks in this spectra do not reflect the power at a given frequency. iii) PSD spectrum is the magnitude spectrum of a signal squared iv) Power spectrum is magnitude spectrum of a signal squared (conflicts with iii)) v) Power spectrum is for periodic time signals (which are discrete in frequency domain) and PSD spectrum is for non-periodic time signals (which are continuous in frequency domain) Divide the PSD of acceleration signal by g^2 (i.e 9.81^2) to convert it from (m/s^2)^2 to g^2. Or divide the time domain acceleration data by g (=9.81) and then obtain its PSD. Here is an example showing how to use spectrum.psd to compute PSD of a signal. Fs = 1000; t = 0:1/Fs:.3; x=cos (2*pi*t*200)+randn (size (t)); Hs=spectrum.periodogram; psd (Hs,x,'Fs',Fs) More details at http://www.mathworks.com/help/toolbox/signal/ref/spectrum.html. Redkap on 29 Feb 2012. Spectrum analysis, also referred to as frequency domain analysis or spectral density estimation, is the technical process of decomposing a complex signal into simpler parts.

First, to significantly improve the Fast Fourier Transform (FFT) speed ratio, by reducing the number of operations, the number of samples in the time series, N, is truncated to the next lowest power of two, 217, leaving N=131,072, thereby reducing the PSD spectrum for trial #1330.
