Abstract
A system may include a memory configured to store an attenuation waveform and control logic. The control logic is configured to receive a synchronizing signal indicative of an operating characteristic of a noise source. In response to a value of a characteristic (e.g., frequency) of the synchronizing signal, the control logic is configured to output the attenuation waveform from the memory if the attenuation waveform is associated with that value of the characteristic of the synchronizing signal. An attenuating noise generated dependent on the attenuation waveform attenuates a noise generated by the noise source.
