Abstract:
1. A controller configured to sense an input object in a sensing region of a sensing device, the controller comprising: drive circuitry coupled to a first transmitter electrode and a second transmitter electrode and configured to simultaneously apply a first modulation signal to the first transmitter electrode and a second modulation signal to the second transmitter electrode, wherein the first modulation signal is based on a first one of a plurality of distinct digital codes and the second modulation signal is based on a second one of the plurality of distinct digital codes; and receive circuitry coupled to a plurality of receiver electrodes and configured to receive resultant signals with the plurality of receiver electrodes, the resultant signals comprising electrical effects associated with the first and second modulation signals; wherein the controller is configured to determine positional information for the input object based on the on the resultant signals.
