Abstract:
1. A processing system for an input device, the processing system comprising: a transmitter module comprising transmitter circuitry, the transmitter module configured to: a receiver module comprising receiver circuitry, the receiver module configured to receive a first resulting signal with a receiver electrode during the first interval, receive a second resulting signal with the receiver electrode during the second interval, and receive a third resulting signal with the receiver electrode during the third interval; a determination module comprising determination circuitry, the determination module configured to compute a first measurement of a change in capacitive coupling between the transmitter electrode and the receiver electrode based on the first resulting signal, compute a second measurement of a change in capacitive coupling between the transmitter electrode and the receiver electrode based on the second resulting signal, compute a third measurement of a change in capacitive coupling between the transmitter electrode and the receiver electrode based on the third resulting signal, and determine positional information for an input object based on the second measurement and a combination of the first and third measurements.
