Abstract
A method of reducing noise generated by pulse width modulation (PWM) signals includes generating a PWM pulse train using a first set of parameter values and modifying the PWM pulse train during a near-field communication so that the PWM pulse train is generated using a second set of parameter values. Modifying the PWM pulse train includes reducing at least one parameter value of the first set of parameter values. The method further includes resuming generation of the PWM pulse train using the first set of parameter values after the near-field communication.
