Filed: 1990-06-07
Abstract: PURPOSE:To reflect the phase relationship of pulse input signals having the phase difference in detail on the value of a counter by generating double-edge pulses at the rise-ups and fall-downs of two pulse input signals. CONSTITUTION:Double-edge-pulse generating circuits 1a and 1b generate pulses for both edges of the rise-ups and the fall-downs of pulse input signals A and B.
