ス列計数回路。 A two-phase pulse train counting circuit that counts a two-phase pulse train consisting of a first-phase pulse train and a second-phase pulse train having a predetermined phase difference from each other. A first gate detects each rising edge of the pulse train and outputs a predetermined pulse, and a first gate detects each falling edge of the second phase pulse train and outputs a predetermined pulse during a high level period when the two-phase pulse train advances in the second direction. a second gate that outputs;
, and first and second counters that respectively count output pulses from the second gate.
