Digital analysis of bursts in the time domain

A technique is described for analyzing bursts and burst-like events with a digital recording system and a general-purpose computer. The waveform of the burst is sampled by an analog-to-digital converter and stored on magnetic tape. The digitized samples are used as input data to an IBM 7094 data processing system for which a burst-analysis program has been written in the FORTRAN language. The analysis of amplitude and shape variations of a burst train is completed without manual processing of the data. This technique is used to analyze the acoustical noise produced by a card punch.
