Abstract
A technique is described in which a minicomputer (PDP8−E) is used to perform signal averaging and Fourier analysis of harmonic content on a stationary or slowly varying repetitive audio frequency waveform. Examples are given of the averaging and analysis process, and the performance of the system in rejecting spurious random or non−synchronized signals is discussed.Keywords
