Abstract:

A processing system for an input device includes a transmitter modules coupled to a plurality of transmitter electrodes including a first set and a second set of transmitter electrodes, the first set and second set being disjoint and having different sizes. The transmitter module is configured to simultaneously transmit a first plurality of transmitter signals with the first set of transmitter electrodes during a first period, and to simultaneously transmit a second plurality of transmitter signals with the second set of transmitter electrodes during a second period, wherein the first period and the second period are non-overlapping. Each of the first plurality of transmitter signals is based on a different sequence of a code, which includes a set of mathematically independent sequences and has a size equal to the size of the first set of transmitter electrodes.
