Abstract
When one calculates the DFT of a sequence of measurements of a random signal, one finds that the values of the elements of the DFT do not tend to “settle down” no matter how long a sequence one measures. In this chapter, we present a brief overview of the difficulties inherent in analyzing the spectra of random signals, and we give a quick survey of a solution to the problem—the method of averaged periodograms.
