MAJORITY SELECTOR Russian patent published in 1998 - IPC

FIELD: redundancy systems which process number-pulse codes, devices for analysis and comparison of pulse sequences. SUBSTANCE: device provides testing of reverse channel counters 4, 5, 6 by means of channel NOR gates 7, 8, 9. In case of failure of reverse counters 4, 5, 6 (they are switched to arbitrary non-zero state), this non-zero signal is received by input of first NOR gate 1 through corresponding NOR gate 7, 8, and 9. Low permitting level at input of first NOR gate 1 results in passing pulse from clock oscillator 10 through inverting input to resetting inputs of reverse counters 4, 5, 6. This results in switching to initial state. EFFECT: increased reliability due to increased stability to recoverable malfunctions when device switches to arbitrary state of memory elements. 2 cl, 1 dwg
