Reducing the gradation level allows the degree of gradation of the driving voltage signal to be within the resolution range of the PWM modulation, and thus PWM modulation can be performed even when the driving voltage signal has a high frequency. Noise-shaping modulation reduces the level of quantum noise near the low frequency range by causing the quantum noise due to digitization, included in the driving voltage signal, to be biased toward the high frequency range side. Of modulation signals with the reduced-gradation level, the components near the high frequency band are cut, while the components near the low frequency range are used to suppress quantum noise and control the driving voltage applied to the motor with a high accuracy.
