Abstract
An amplitude calculation apparatus or an amplitude calculation program of an output signal of an encoder dividing a resurge waveform into a predetermined number of angle areas, presetting and storing coefficient α of the A-phase and the coefficient β of the B-phase corresponding to the divided angle areas, the coefficients being set so that αA+βB approximates the radius of the theoretical resurge waveform, calculating the radius of the resurge waveform as αA+βB, and making the calculated radius the amplitude of the output signal of the encoder or converting a phase angle θ of a quadrant n to a phase angle θ′ of the quadrant 1, and calculating the radius of the resurge waveform as α|A|+β|B|, whereby the circuit size of the apparatus for calculating the resurge radius from the output of the encoder is reduced and the processing time by software for calculating the resurge radius is shortened.
