Abstract
The present invention relates to digital circuit processing and provides a position indication device and a position indication method. In order to improve positioning accuracy of the position indication device without degrading its sensitivity, a position indication device is provided. The device comprises: a voltage dividing circuit connected with a resonant circuit and a rectifying and filtering circuit. The voltage dividing circuit obtains a predetermined proportion of a signal output from the resonant circuit and outputs it to the rectifying and filtering circuit. The present invention is applicable to digital handwriting pens.
