摘要：
A signal processing method for a touch panel is provided. The touch panel includes several capacitor electrodes. The method includes the following steps. Detection values are provided according to self-capacitance changes of the capacitor electrodes. The detection values are then low-pass filtered by a filter structure to generate several filtered values. A position where a touch event occurs on the touch panel is determined according to the filtered values.
