A method for reducing the effect of a noise impulse in a digitizing panel which includes a resistive layer is disclosed. The method includes the steps of generating a signal when an object is in proximity to the digitizing panel, amplifying the signal with an amplifier, detecting the presence of the noise impulse coupled to the resistive layer, and disconnecting an input of the amplifier from the resistive layer in response to detecting the noise impulse. In addition, a digitizing panel is disclosed which includes a resistive layer for providing a signal when an object is in proximity to the digitizing panel.
