ABSTRACT:
A system for the cyclical time-compression of a continuous physiologic waveform provides scan-type display without loss of data during retrace by recording original data at one rate during a retrace-trace cycle, and read-out at a faster rate during the trace period for the compressed display. A feature of the system is use of a single random-access memory which has only the relatively small capacity for storing the data entered from the beginning of the retrace in a time compression cycle until readout at trace period in that cycle begins.
