Abstract
A stylus used to interact with a plurality of positioning transmission electrodes includes a receiver and a demodulation circuit. The receiver receives an uplink signal carrying a plurality of positioning signals which are transmitted from the plurality of positioning transmission electrodes. The demodulation circuit, coupled to the receiver, demodulates the uplink signal to generate at least one positioning signal among the plurality of positioning signals.
