Abstract
Apparatus for producing an analog signal--having a relative amplitude that is indicative of the direction and rate of rotation of a shaft--from a pair of pulse streams provided by a shaft encoder coupled to the shaft. The invention includes circuitry for comparing the phase relationship between the signals to determine direction, for generating a digital pulse of a fixed pulse-width for each pulse contained in one of the pulse streams, and integrating the time or inverted form of the digital pulse, depending upon the determined direction, to produce the analog signal.
