Abstract
A system and method are present for generating a modulated waveform. A timer is configured to generate a first modulated waveform signal, and an adder module is configured to calculate a delay. The delay includes at least one of an edge fractional delay and a dead time fractional delay. A delay module is operably coupled to the timer and the adder module. The delay module is configured to delay at least one of a rising edge of the first modulated waveform signal and a falling edge of the first modulated waveform signal by the delay to generate a second modulated waveform signal that has a higher frequency resolution than a frequency resolution of the first modulated waveform signal.
