1. A controller for a position sensor, wherein the controller comprises:

  • drive circuitry configured to simultaneously transmit a first signal with a first transmitter electrode and a second signal with a second transmitter electrode, where the first and second signals are distinct signals based on distinct digital codes; and

    receiver circuitry configured to receive electrical effects with at least one receiver electrode, wherein the electrical effects are associated with the first and second signals, wherein the controller is configured to determine a position-based attribute of at least one input object based on the electrical effects.
