Abstract:
A method for filtering X and Y coordinate signals of a resistive digitizer, comprising:a) connecting power to a first coordinate plane of a resistive digitizer,b) connecting a first sense signal to a first filter input by closing a first switch and producing a first filtered signal,c) reading said first filtered signal,d) disconnecting said first sense signal from said first filter input by opening said first switch,e) disconnecting power from said first coordinate plane,f) connecting power to a second coordinate plane of said resistive digitizer,g) connecting a second sense signal to a second filter input by closing a second switch and producing a second filtered signal,h) reading said second filter signal,i) disconnecting said second sense signal from said second filter input by opening said second switch,j) disconnecting power from said second coordinate plane.
