PROBLEM TO BE SOLVED: To provide an angular position detector for detecting an angle of a resolver capable of reducing problems such as vibration and noise of motor due to an influence of noises overlapping with output when the transmission characteristics of RD conversion means is expanded or the output improves spatial resolution.SOLUTION: The angular position detector includes: RD conversion means 105 that converts an angle of a resolver 101 into a digital value and outputs the same, a variable digital filter 106 which has a low-pass characteristic and is capable of varying a shut off characteristics by changing the setting of a constant. The output of the RD conversion means 105 is output via the variable digital filter 106. |
