<p>The present invention provides for a method of reducing the effect of a noise impulse in a digitizing panel (14) having a resistive layer (28) and wherein a signal is generated when an object is in proximity to the digitizing panel (14), and including the steps of amplifying the signal with an amplifier (36), detecting the presence of the noise impulse coupled to the resistive layer (28), and disconnecting an input of the amplifier (36) from the resistive layer (28) in response to detection of the noise impulse. In addition, a digitizing panel (14) is disclosed which includes a resistive layer (28) for providing a signal when an object is in proximity to the digitizing panel (14) and means (44) for disconnecting an amplifier thereof from the resistive layer (28) in response to detction of the noise impulse. <IMAGE></p> |
