A/b-phase signal generator, rd converter, and angle detection unit

摘要: An A/B-phase signal generator wherein an up/down count unit 52C counts up by up-count command or down a down-count at fixed intervals, angle comparison 51 compares the result ACNT of with input rotation .theta. and generates request, which is request 52B previous next only when are both requests requests, respectively, pulse 53 receives least significant bit second outputs A-phase B-phase signal.
