Abstract
Abstract This disclosure relates to a system for monitoring and storing the amplitude of a plurality of simultaneously occurring waveforms and simultaneously displaying the history of the waveforms over a predetermined interval of time. The amplitudes of the waveforms are sampled at closely spaced intervals of time and stored in a multi-station memory system. Periodically each stored waveform is updated and the oldest sampled and stored amplitude discarded.
