QUADRATURE-TO-SERIAL PULSE CONVERTER

摘要

A converter for converting a quadrature pulse train into first and second serial pulse trains which respectively correspond to opposite directions of travel of a generator supplying said quadrature pulse train. The converter comprises a first circuit responsive to said quadrature pulse train for producing a third serial pulse train in which the number of pulses correspond to the total number of pulse edges in said quadrature pulse train, and a second circuit means responsive to said third pulse train and said quadrature pulse train for forming the pulses of said first and second pulse trains. The second circuit includes a network for supplying the formed pulses to one output terminal when said generator is traveling in one direction to make up said first pulse train and for supplying the formed pulses to another output terminal when the generator is traveling in the opposite direction to make up said second pulse train.
