Abstract
A system and method generate a pulse width modulated signal having variable duty cycle resolution. A hardware uses minimal hardware to improve the PWM duty cycle resolution up to 0, such that highest possible resolution of a waveform can be obtained, including a sine wave. An embodiment of the invention uses a microcontroller, a divide by W counter, a delay circuit, a flip-flop, and a logic gate.
