GRAY-CODE PULSE COUNTER Russian patent published in 1998 - IPC

FIELD: pulse engineering. SUBSTANCE: Gray-code pulse counter has first through fifth input buses 1 through 5, output bus 6, common bus 7, control D flip-flop 8, and control unit 9. Each counter bit incorporates D flip-flop 10 (10-1, 10-2, 10-3), NOR gate 11 (11-1, 11-2, and 11-3). First and second bits of counter incorporate EXCLUSIVE OR gate 12 (12-1 and 12-2) and OR gate 13 (13-1, 13-2). Input bus 1 is connected to first control inputs of D flip-flops 8, 10-1, 10-2, and 10-3. EFFECT: improved design. 2 dwg
