STUDY OF ON-LINE DATA ANALYSIS WITH A HYBRID COMPUTER.

Abstract

Hybrid Computer programs were developed to accept data in analog form and simultaneously to perform selected analysis and reduction procedures in real time, the results appearing as continuous analog outputs. Analog circuits with parallel logic removed interference spikes from the original data, separated the frequency components of the signal using analog band-pass filters, measured the power in these frequency bands, and formed a continuous record of the correlation coefficient of two signals. Hybrid programs calculated, and outputed in analog form, the amplitude probability density and the auto- or crosscorrelation functions; initial data conditioning and final display utilized analog circuits, but the calculation was performed on a digital computer linked by a-d and d-a converters and control circuits.
