1. A method of detecting events with a touch sensor panel device comprising:

  • applying a first stimulation signal having multiple different frequencies to a first touch sensing node of the touch sensor panel device to detect a position of an object touching the touch sensor panel device at or near the first touch sensing node;

    while applying the first stimulation signal, sensing an output of the first touch sensing node for each frequency of the stimulation signal that was applied to the first touch sensing node to thereby provide multiple outputs;

    determining a final result based on all or a plurality of the multiple outputs of the first touch sensing node; and

    utilizing the final result to determine the position of touch, near touch or hover location on the touch sensor panel device.
