Abstract:
A method is disclosed that includes allowing both frequency and amplitude of a periodic waveform to be adjusted. The method also includes creating the periodic waveform having the frequency and the amplitude. The periodic waveform is coupled to at least one control signal. The at least one control signal is provided to an output suitable for coupling to an actuator of an electronically controlled device. An apparatus and computer program product are disclosed.
