A POWER-SPECTRUM PROGRAM FOR THE IBM 650 COMPUTER

Abstract

The power-spectrum program described in this report uses for its input the autocorrelation function, as calculated by the program described in DRL AF Technical Memorandum No. 51. The spectrum program prepares a table of the cosines which will be needed and then generates appropriate look-up instructions for the cosines during the computation. This is considerably faster than recomputing each cosine as needed. The output of the spectrum program gives the frequency interval, the raw spectrum, the Hammed and Hanned spectra,AND THE CUMULATIVE OR INTEGRATED VERSIONS OF THESE THREE SPECTRA. (Author)
