Abstract
A digital system for measuring an input quantity includes an input mechanism for providing a first input in response to an input quantity to be measured, a stepper motor for providing a second input, a measuring apparatus connected to the input mechanism and to the stepper motor such that the measuring apparatus provides an output when the first and second inputs reach a predetermined relationship, and a circuit connected to the stepper motor and to the measuring apparatus for stepping the stepper motor from a reference position and for counting the steps of the stepper motor until the measuring apparatus provides the output.
