Abstract
The present invention is directed toward providing a system and method of reducing RF interference in switching amplifiers without degrading performance. In one embodiment, the sampling rate of coarse high voltage modulated pulsewidths are increased relative to the sampling rate of fine lower voltage modulated pulsewidths. This increase in the sampling rate of coarse high voltage modulated pulsewidths results in a reduction in EMI.
