Abstract

PURPOSE:To obtain a signal which is linear throughout the entire range of rotation, by generating a plurality of differently-phased periodic function signals in accordance with a rotational angle and by composing complementarily a part having an excellent linearity of a rotational-angle-to-signal level property out of these signals. CONSTITUTION:A rotational-angle detecting part 1 detects a rotational angle theta of a rotary shaft 2 and generates a plurality of differently-phased periodic sunction signals corresponding to the angle theta. A linear region detecting circuit 4 monitors the levels of the periodic function signals A and B delivered from the detecting part 1 and detects one signal (A or B) generating the level belonging to a region in which the linearity of the rotational-angle-to-signal level property is excellent. In a composing circuit 5 the signal detected by the linear region detecting circuit 4 is composed, whereby a rotational-angle signal Stheta having excellent linearity is obtained throughout the entire range of rotation.
