摘要： A measurement range is divided into a plurality of sections, a binary coded signal is generated at each division point, small section signals are generated at a predetermined interval between the binary coded signals, the binary coded signals are weighted by angles, and the small section signals are added or subtracted to or from the weighted signal to interpolate between two binary coded signals. Since the increment signals generated between the adjacent absolute signals is used as an interpolation signal between the absolute signals, the measurement accuracy is enhanced without increasing the number of elements for generating the absolute signals. The measured angle can be accurately read by adding or subtracting the increment signals to and from the weighted signal of the absolute signal.
