Abstract
A pulse signal generator suitable for generating a two-phase pulse signal required as information of a rotation angle of a motor from a motor control device is provided. According to an embodiment, the pulse signal generator includes: a compensation unit that outputs a compensation signal for compensating for the deviation between the angle information representing the rotation angle of the rotor provided in the resolver and the fed back angle information; a counter pulse output unit that outputs a counter pulse having a frequency corresponding to the compensation amount of the compensation signal and code information representing the sign of the compensation signal, and a pulse processing unit that outputs a count value by a counter as the angle information, which counts the pulse according to the code information, the pulse processing unit generating two-phase pulse signals PA and PB using the values of the counter.
