Abstract
A method for generating a pulse width modulation (PWM) signal, by a processor communicatively coupled to a system memory element, is provided. The method computes, by the processor, a coarse adjustment PWM output signal and a modified fine adjustment input signal, using a low speed clock rate; performs, by the processor, a fine adjustment to the coarse adjustment PWM output signal, using a high speed clock rate, based on the modified fine adjustment input signal; and generates an increased resolution PWM output signal, by the processor, based on the fine adjustment.
