"This report is a handbook on spectrum windows. The subject is introduced by a discussion of the fundamentals of spectrum analysis, which shows how the four kinds of window arise in the practical estimation of spectra. The modern direct method of computation using sampled data and the DFT is emphasized, and it is shown that the effects of discrete analysis on the computed spectrum can be described completely by the appropriate spectrum window. Exact closed-form expressions are derived for the spectrum windows corresponding to most of the functions that have been proposed for use as data windows; the cases of continuous and discrete analysis are treated separately for each function. Some of these results are not available elsewhere. The characteristics of the spectrum windows are also presented in graphical form"--Abstract, page 1. Signal processing. Power spectra.
