Document Type and Number:
WIPO Patent Application WO/2018/051388
Kind Code:
A1
Abstract:
[Problem] To provide an analog circuit for use in a position indicator, which is of low power consumption and of high noise-resistance. [Solution] An analog circuit 90 according to the present invention is connected to an electrode 21 that receives a control signal by electrostatic coupling, and comprises: an edge detection unit 71 that detects a rising edge and a falling edge of the control signal received by the electrode 21; and a waveform restoration unit 72 that restores the waveform of the control signal on the basis of the rising edge and falling edge detected by the edge detection unit 71.
