ABSTRACT:
The characteristics of an a.c. waveform are determined by measuring the time interval between the instant when the waveform crosses a first reference threshold and the instant when it crosses another threshold. The second threshold is varied to obtain a series of time interval measurements from which a point by point reconstruction of the waveform can be made. The technique has the advantage that it can be used to characterize waveforms whose arrival time is indeterminable.
