Abstract
At least some aspects of the present disclosure provide for a system. In some examples, the system includes a pulse width modulation (PWM) generator configured to generate a PWM signal. The PWM generator generates the PWM signal by generating a first signal having a first dithering profile and a first frequency bandwidth, generating a second signal having a second dithering profile and a second frequency bandwidth greater than the first frequency bandwidth, modulating the second signal with the first signal to generate a dual random spread spectrum signal, and generating the pulse width modulation signal according to the dual random spread spectrum signal.
