Patent ID: 7684462

Claim:
A system for providing frequency control, the system comprising: a pseudorandom signal generator configured to generate a digital signal, the digital signal associated with at least an N-bit datum, N being a positive integer; a digital-to-analog converter configured to receive the digital signal and generate a first control signal; an output signal generator configured to receive the first control signal and generate at least a first output signal associated with a frequency; a pulse-width-modulation generator configured to receive at least the first output signal; and a first controller configured to receive a load signal and output a second control signal to the output signal generator, the load signal indicating an output load; wherein: the N-bit datum represents a pseudorandom number; and the output signal generator is further configured to process information associated with the first control signal and the second control signal and generate at least the first output signal associated with the frequency based on at least information associated with the first control signal and the second control signal.
