1. A position indicator operatively associated with a position detector that transmits a driving signal, said position indicator comprising:
a signal processing module including
a receiving electrode adapted to receive the driving signal;an amplifying circuit coupled to said receiving electrode, and amplifying the driving signal received by said receiving electrode to generate an amplified signal;an oscillating circuit coupled to said amplifying circuit for receiving the amplified signal therefrom, and generating an output signal that oscillates for a time period upon satisfaction of a predetermined threshold condition associated at least with the amplified signal and a predetermined trigger level; anda transmitting electrode coupled to said oscillating circuit, and adapted to transmit the output signal generated by said oscillating circuit. |
