Blackman-tukey method

WebMay 11, 2012 · Windowing, as it was traditionally developed, was intended for the Blackman-Tukey method of power spectral density of estimation. This is the general form of the correlogram methods, whereby the discrete-time Wiener-Khinchin theorem is exploited. Recall this relates the autocorrelation sequence to the power spectral density … WebArand software for Blackman-Tukey Spectral Analysis This repository contains the latest and presumably last version of the Arand spectral analysis software package, developed by Philip Howell of Brown University. I am hosting it here for posteriority reasons as to the best of my knowledge it is no longer available elsewhere.
