ABSTRACT:
An audio noise mitigation approach. For one aspect, a first voltage associated with a first power management state is provided. A signal responsive to an indication associated with at least a first type of periodic exit event is received and responsive to the signal, a transition to a second voltage associated with a second state is initiated, a rate of the transition to the second voltage being slower than a similar voltage transition initiated in response to a non-periodic exit event.
