Abstract
Determining an amount of rotating a vector according to a result of comparing the rotated vector with a predetermined phase and rotating the vector according to the determined amount of rotating the vector are repeated to acquire the determined amount of rotating the vector as a rotation angle of a rotation shaft. Based on the thus acquired amount of rotating the vector, a rotation angle change signal is generated for acquiring a state of a change of the rotation angle of the rotation shaft. A signal indicating to increase or decrease a fixed amount is generated for increasing or decreasing the amount of rotating the vector according to the result of the comparison.
