Abstract
A touch sensing system includes a capacitive touch panel, a controller, and a signal source. The capacitive touch panel is used for a user to perform inputs. The controller is coupled to the capacitive touch panel, configured to scan the capacitive touch panel. The signal source is configured to provide a periodical signal for coupling to the user, such that the periodical signal can be coupled to the capacitive touch panel via the user.
