摘要:
A graphic curve digitizer is disclosed wherein the x-y coordinate values of a response curve (made electrically conductive) are obtained by a digitally controlled x-y conductive probe and electronic system sensing when the probe contacts the curve by the voltage signal existing in the conductive curve due to the antenna effect of the conductive curve in an environmental alternating current electromagnetic field.
