Zusammenfassung: | Determination of phases of multiple stimulation signals to be simultaneously applied to a touch sensor panel is disclosed. A matrix may be determined that is invertible and has a gain greater than one, where each row of the matrix may represent a single step among multiple steps needed to compute values for generating an image of touch, each column of the matrix may represent a drive line of the touch sensor panel to be stimulated, and each element of the matrix may represent the phase of the stimulation signal to be applied to a particular drive line in a particular step. For each step, stimulation signals having phases in accordance with the matrix elements may be simultaneously applied to the drive lines of the touch sensor panel. |
