Abstract : A 16-channel all-semiconductor commutator was designed and field tested in the T361, T368, XM112, and TOW missile-telemetry systems. Of approximately 200 electronic units tested, all performed satisfactorily under accelerations up to 14,000 g and 180 rps. The design concept is based on a code-operated multiposition switch that is controlled by pulse and digital circuitry. For any switch configuration, only one input signal reaches the output terminal because of the AND gates. The binaries, therfore, change states and commutate from one channel to another with the generation of each input pulse. Theoretical details of the design and operation of the commutator are described and illustrated. (Author)
