Abstract
A system may include a memory configured to store instructions and a processor. The processor may be configured to execute the instructions to cause the system to determine a PWM frequency of the input PWM signal and generate a first PWM signal to power a first light emitting diode (LED), a second PWM signal to power a second LED, and a third PWM signal to power a third LED. Each of the first PWM signal, the second PWM signal, and the third PWM signal may have the PWM frequency of the input PWM signal and may be in phase with the input PWM signal.
