Abstract : An estimate is made of the accuracy with which the 'spectrum' of a finite sample of noise approximates the spectrum of the original noise from which the sample was taken. The sample is considered to be spliced into an endless loop to form a periodic function, and all measurements are assumed perfect. (Author)
