Abstract
An apparatus aims at detecting an angle of a rotating shaft as a train of bits. A first signal including a train of pulses corresponding to angle intervals of a rotation of the rotating shaft is inputted to the apparatus, and a second signal including a train of clock pulses whose clock cycle is a positive integer submultiple of a pulse cycle of the first signal is inputted to the apparatus. In the apparatus, a first counter is indicative of a higher-order of the train of bits, and counts up or down in synchronization with the pulse cycle of the first signal. A second counter is indicative of a lower-order of the train of bits, and counts either up or down in synchronization with the clock cycle of the second signal. The second counter is cleared in synchronization with the pulse cycle of the first signal.
