Abstract

PURPOSE: To detect the net positive RPM at all times, while reducing the size and cost of a detector, by providing a reversible counting circuit, which is operative to count the positive and reversed pulses to a level higher than a frequency-dividing ratio N and a reversed pulse number M, to clear the circuit when the content reaches N.
