Abstract
A multi-channel electronic waveform recorder, for storing waveform data and time of occurrence information, i.e., a 'time-tag', for each stored value of an input waveform, is disclosed. Specifically, each channel of the waveform recorder compares a previously stored value of a corresponding input signal to a current value, and stores the current value whenever the difference between the input signal and the previously stored value is a predetermined amount.
