Web• Can think of average power as average energy/time. • An energy signal has zero average power. A power signal has infinite average energy. Power signals are generally not integrable so don’t necessarily have a Fourier transform. • We use power spectral density to characterize power signals that don’t have a Fourier transform. 2. 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.
