WebCalculation of the Power Spectral Density. It was mentioned earlier that the power calculated using the (specific) power spectral density in w/kg must (because of the mass of 2-kg) come out to be one half the number 4.94 × 10-6 w shown in Fig. 5. That this is the case for the psd used, so that Parseval's theorem is satisfied, will now be shown. http://www.igpphome.ucsd.edu/~cathy/Publications/Preprints/spectrum.pdf
