ABSTRACT:
A circuit for determining the duration range of each incursion by a variable signal on one side of a selected level uses a comparator with a reference crossing level to develop a squared waveform pulse output. Each pulse is integrated and the value gated to a plurality of comparators. The comparators have inhibit interconnections and reference inputs for the desired ranges.
