DESIGN OF AN ON-LINE INPUT-OUTPUT SYSTEM FOR THE M3 COMPUTER

Abstract

A proposed design of an on-line input-output system for the 143 computer is described. Although this system is primarily designed for correlation analysis of two channels of physiological data, it is capable of digitizing two channels of analog signals with frequency components in a spectrum from 0.5 cps. to 100. cos for other analysis. The accuracy of the analog to digital conversion technique employed is analyzed. The minimum number of samples required for an accuracy of 10% is limited to 1000 samples for crosscorrelation and 5000 samples for autocorrelation.
