Abstract

A position-measuring system in which an improved digital to analog converter accepts an error signal from a position measuring transducer, the error signal being processed to be a digital signal representation of the magnitude and two-state direction of a positional error. The system is constructed to operate as if the error signal input had three states, two directional states and an intermediate "dead zone."
