Abstract
A stylus sensing circuit includes a receiving circuit, a demodulation circuit and a detection circuit. The receiving circuit receives a downlink signal from a stylus, wherein the downlink signal includes a plurality of frequency signals. The demodulation circuit, coupled to the receiving circuit, demodulates the downlink signal to extract each of the plurality of frequency signals. The detection circuit, coupled to the demodulation circuit, chooses one of the plurality of frequency signals to perform a signal processing.
