Abstract The system includes coordinate moving information picking up device and position indicator; the former includes a working area comprising X and Y axle signal lines and surrounded by coils, a scanning circuit, a signal processing circuit and a sync discriminating circuit; the signal processing circuit includes a pulse generator to produce two pulse signals fed to the sync discriminating circuit separately via the working area and directly; and the position indicator located in the working area incldues tuning circuit, pulse width controlling circuit and button circuit. The method detects the time of transferring the two signals and determines coordinate motion and other data base on the time difference.
