DEVICE FOR DECODING OF GROUP CODES Russian patent published in 1994 - IPC

FIELD: transmission of discrete information. SUBSTANCE: device for decoding of group codes includes shift register 1, storage 4, recalculator 5, register 7, first 10 and second 11 comparators, first 12 and second 13 NAND gates, first 15 and second 16 D flip-flops, inverter 17, first 18 and second 19 buffer registers, selector 21 of cycle synchronization. Recalculator 5 has first and second four-digit binary counters and AND gate. Selector 21 of cycle synchronization includes D flip-flop, four-digit binary counter, four-input NAND gate, current-setting element and inverter. EFFECT: increased informativity of device due to simultaneous decoding by two channels. 3 cl, 3 dwg, 1 tbl
