Abstract
In an apparatus, a timing signal outputting unit outputs a timing signal every time interval. The time interval is shorter than a pulse time interval of the pulse signal. A first storage unit stores first information relative to each pulse time interval of the pulse signal. A second storage unit samples a value of the sensor signal each time the timing signal is outputted, and stores the sampled values so that the sampled values are associated with pieces of second information, respectively. Each of the pieces of second information is relative to each of sampled timings of the values. A calculating unit calculates a rotation angle of the rotation shaft corresponding to each of the values of the sensor signal based on a relationship between the first information and the pieces of second information.
