A technique for processing coronary hemodynamic data with a small hybrid computing system

This report describes the program for utilizing a small hybrid computing system to process coronary arterial flow and pressure signals obtained from chronically instrumented, conscious animals and discusses the advantages and disadvantages of the hybrid approach. Extensive analog preprocessing using parallel logic facilitates formation of data during the experiment and minimizes later editing. Moreover, it allows the digital portion of the program to be much smaller and more general than similar applications using only digital systems. Final output consists of an ink-jet recording of the analog signals, a printout of the digital results, and CalComp plots.
