This is a real-time waveform analysis routine. The waveform is sampled and continuously displayed. The waveform can be frozen, via the sense switches, and the minimum and maximum values of the waveform determined (and indicated). Two cursors, controlled by the A/D Converter pots, are displayed congruous to the waveform; their horizontal and, vertical absolute differences are displayed. The routine is particularly useful for analysis of physiological signals, i.e., calculation of QRS width, S-T interval, R-R interval, etc.
