Abstract:
In one embodiment, a method receives a pulse width modulation signal. A value that is a function of the pulse width modulation signal is determined. The value is used to modulate a switching frequency of the pulse width modulation signal to generate a modulated pulse width modulation signal. The applied value reduces electro-magnetic interference from tones in the modulated pulse width modulation signal.
