ABSTRACT:
The invention provides new potentiometer-type function generators that have (1) a resistance element having a two-dimensional contact surface with boundaries arranged so that a non-uniform voltage distribution is produced when the resistance element is electrified and (2) a contact member which is mounted so as to permit relative movement in two different directions between it and the contact surface of the resistance element.
