摘要
A rotational angle detecting apparatus having a rotation detector that outputs, as a rotor coupled to a rotating member rotates, first and second detection signals, which have predetermined amplitudes, the same cycle, and a phase difference of a quarter wavelength, a memory for storing the first and second detection signals, and a control unit. The control unit detects the rotational angle of the rotating member by averaging the amplitudes of the first and second detection signals according to the area in which the first detection signal lies.
