On the variance of time and frequency averages over modified periodograms

View publication

Abstract

Expressions of a common form will be given for the variance of spectral estimators which are either time or frequency averages over modified periodograms. A modified periodogram is a generalization of the usual periodogram in which the time sample is premultiplied by a data window. Such estimates include almost all in common use and this discussion should clarify the relationships between practical alternatives.
