Abstract
A function generator is provided which establishes an output signal according to a functional relationship determined by the preformed contour of an easily precut cam member. The function generator includes a variable gain controller section coupled to a proximity sensing motion balance servomechanism which varies the gain of the controller according to the sensed proximity of the servomechanism to the edge of the cam member without physical contact therewith. The cam member's position is in turn determined by an input signal which may be related to the controller input signals or may be an independent signal from a remote source. The gain and consequently the output of the controller is varied according to the functional relationship determined by the precut contour of the cam member.
