Abstract
An input device is configured to detect signals from of an input object. Examples include acquiring a first signal on a first sensor electrode of the input device; acquiring a second signal on a second sensor electrode of the input device; combining the first signal and the second signal to produce a combined signal; demodulating the combined signal to determine an in-phase component of the combined signal and a quadrature component of the combined signal; and combining the in-phase component and the quadrature component to determine signal magnitude information.
