Abstract
Embodiments of the invention generally provide an input device that simultaneously transmits a multiplexed signal across two or more transmitter electrodes used in touch detection. The multiplexed includes two or more component signals that are transmitted on respective electrodes (or channels). The component signals are then decoded and correlated to indicate a positional location of an input object. Various multiplexing schemas—e.g., code division multiplexing, frequency division multiplexing, orthogonal frequency division multiplexing, and the like—may be used to generate the multiplex signal and then demultiplex the received results.
