The prewhitened spectrum 1s the result of. performing the same analysis on data which has been convolved with a special high-pass fil- ter. The corrected spectrum results from the quotient of the prewhitened spectrum and the frequency spectrum of the high-pass filter, and represents an estimate of the spectrum of the corresponding Infinite signal from which the sample data was derived. 51.
