Abstract
PURPOSE: To simplify the circuit constitution and enhance the reliability by making a circuit after a phase detecting circuit to one system.
CONSTITUTION: Plus phase difference or minus phase difference is pulsated in accordance with the lead or lag of phase of two signals S (ψ1) and S (ψ2) by a first and a second phase detecting circuits 14, 15, and plus phase difference pulse group or minus phase difference pulse group is taken out N times. While they are up and down counted by an common average counter 16, they are frequency divided by 1/N and the output thereof is collected N times by a common data counting circuit 17 to obtain an average phase difference data.
