Patent abstract
A position detector has a peak detector for detecting peak values of an A1 signal and a B1 signal serving as output signals of an analog to digital (AD) converter, an offset/amplitude correction section for generating an A2 signal and a B2 signal by correcting offsets and amplitude errors using the peak values detected by the peak detector, and a position data conversion section for converting the sinusoidal signals of an A phase and a B phase into position data.
