Abstract
A system for a capacitive sensing device includes transmitter electrodes configured to transmit transmitter signals, receiver electrodes configured to receive resulting signals including effects corresponding to the transmitter signals. The system further includes dual nodes corresponding to a first capacitive coupling between the transmitter electrodes and the receiver electrodes, and primary nodes corresponding to a second capacitive coupling between the transmitter electrodes and the receiver electrodes. The first capacitive coupling is less than the second capacitive coupling.
