  • Patent number: 9104267
    Abstract: A capacitive multi-touch system includes a touch sensor pane, a front-end circuit, and a digital signal processor. The touch sensor panel generates a capacitance signal corresponding to a touch input. The front-end circuit converts the capacitance signal to a sensing channel signal. The digital signal processor receives a common voltage (VCOM) from a display device, calculates a noise interval of two neighboring noise peaks of the common voltage, and performs a noise filtering operation on the sensing channel signal using a noise filter path. The noise filter path is selected from a plurality of noise filter paths based on the noise interval.
