Abstract
A process and apparatus for generating an output signal whose frequency varies according to a modulation scheme, the process including the steps of providing a dither generator for receiving a first input signal representative of a clock frequency and for generating, according to the modulation scheme, a dithered output signal representative of the first signal at a dithered frequency; providing a DSP for receiving the following input signals: the signal at the dithered frequency and a second signal representative of a clock frequency, the DSP adapted to generate a processed output signal representative of the maximum frequency of the second signal; wherein the modulation scheme has a periodic ultrasonic modulating wave.
