A system and method for pulse edge synchronization. According to an embodiment, a first series of PWM signals that may drive a first device wherein each pulse in this series has a rising edge and a falling edge. The system and method further includes a second series of PWM signals that may drive a second device wherein each pulse in the second series of pulses also has a rising edge and a falling edge. These series of pulses are then synchronized such that each rising edge in the first series occurs simultaneous to a falling edge in the second series and vice versa. Such a system and method reduces the level of acoustic noise generated between the two motors. Further, synchronizing the rising and falling edges of the PWM pulses reduces and often eliminates stray EMI. |
