Summary:A PWM processor (30) is disclosed that includes a modulator (14) and a carrier signal (12) generator that generates first and second carrier signals (32,34), the modulator unit generating a PWM signal corresponding to a reference signal supplied thereto by the alternative use of the first and second carrier signals. A PWM processor is also disclosed that includes a modulator, a carrier signal generator, a perturbation unit, and a beat frequency component predictor, the modulator generating a PWM signal from a reference signal to which a perturbation signal has been added so as to remove a frequency component corresponding to a beat frequency of a mechanical system driven by the PWM signal such that a beat frequency of the mechanical system is not excited by the PWM signal. Related methods of generating PWM signals are also disclosed.
