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