ROTATION ANGLE DETECTING DEVICE

A detecting unit outputs a first output value varying with a rotation angle of a rotary body in a first cycle and outputs a second output value varying with the rotation angle in a second cycle. The variation in the second output value is different from the variation in the first output value in a p...

Zusammenfassung:	A detecting unit outputs a first output value varying with a rotation angle of a rotary body in a first cycle and outputs a second output value varying with the rotation angle in a second cycle. The variation in the second output value is different from the variation in the first output value in a positive/negative sign. A magnitude relationship between the first output value and the second output value changes with variation in the rotation angle at rotation angles during the first cycle. A selector unit selects, from the first output value and the second output value, a value of at least a minimum value and a maximum value of the first output values corresponding to the rotation angles. A computing unit computes, on the basis of the selected value, a value related to the rotation angle.
