Zusammenfassung:PROBLEM TO BE SOLVED: To provide: a signal duty detecting apparatus detecting a duty of a PWM signal by counting signals, among signals present in a preset period of the PWM signal, having a predetermined level or higher; and a motor driving apparatus comprising the same.SOLUTION: Provided is a signal duty detecting apparatus including: a level detector detecting levels of input signals; a counter counting the levels detected by the level detector; and a duty calculator calculating a duty of the input signals on the basis of the levels counted by the counter. Also provided is a motor driving apparatus comprising the same.
