1. An electronic device, comprising:

  • a processing unit;

    a memory; and

    a haptic actuator;

    whereinthe memory is operative to store instructions for generating a plurality of input waveforms to drive the haptic actuator; and

    the processing unit is operative to determine a delay to be provided between alternating input waveforms provided to the haptic actuator, the delay operative to suppress a higher order resonance mode response of an actuator mass of the haptic actuator.
