Abstract
In one or more embodiments, a fixed time interval for a system is determined. The fixed time interval corresponds to time between clock ticks. A random time interval is determined based on the fixed time interval and an offset. One or more electronic components affixed to a motherboard are transitioned to a new power state when the random time interval has elapsed. By introducing a randomization to the timing element to a control signal that drives the power state transition, a periodicity for the system is disrupted. The disruption in periodicity mitigates acoustic noise generated by vibrations in electronic components and motherboards affected by current and/or voltage transitions.
