... Up: No Title Previous: Mean power spectrum . ... Clearly, this does not imply that the integrands should be equal point-by-point; in fact, there is an infinity of integrands that would meet the integral criterion, each for a different functional basis. It is a matter of interpretation to associate the integrands with an energy density. ... It takes some time and thought to get comfortable with the idea that the Fourier power spectrum is not the absolute answer to spectral energy distribution. ...
