Glen E. Ellis, Boston,R. L. · Defense Technical Information Center (DTIC) · 1965
The report is a discussion of a numerical procedure for computing power density spectral estimates from sampled time series records following the methods of Blackman and Tukey. (The Measurement of Power Spectra', Dover Publications, Inc., New York, 1958). SPECT is the computer program written for the CDC 1604 digital computer for this purpose, and a complete listing along with sample data and output have been included. (Author)
