ABSTRACT:
A signal processing apparatus for a semiconductor position sensing device has an impedance element connected to one output terminal thereof. When a distance to an object is to be detected, an impedance of the impedance element is varied until the outputs of the sensing device substantially balance. The distance to the object is determined by the impedance of the impedance element when the outputs balance.
