Abstract : This report contains a discussion of the changes made to a Spectrum Analysis and Display Computer Program reported in document AD 752-113. The program displays a pictorial representation of the power spectral density of an analyzed signal, as well as estimates of: (1) Blackman-Tukey Bandwidth, (2) signal noise bandwidth, (3) 6 dB bandwidth, all about a peak value within a designated spectral region, (4) signal noise power, (5) dB power (both within the designated spectral region), (6) estimated peak amplitude of the signal, (7) frequency at the peak, (8) the mean frequency within the 6 dB bandwidth, and (9) the signal/noise ratio at the peak.
