MEAN SIGNAL SELECTOR Russian patent published in 2001 - IPC

FIELD: electronic engineering; systems and devices developed by using hot-reserve method. SUBSTANCE: device has first, second, and third relay-switching amplifiers whose noninverting inputs are connected, respectively, to first, second, and third inputs of device; novelty is introduction of first, second, and third switches, first, second, and third biconditional gates whose first inputs are connected, respectively, to outputs of first, second, and third relay- switching amplifiers and second inputs are connected, respectively, to outputs of second, third, and first relay-switching amplifiers; inverting inputs of the latter are connected, respectively, to third, first, and second inputs of device which are connected, respectively, to signal inputs of third, first, and second switches; control inputs of the latter are connected to outputs of second, third, and first biconditional gates, respectively; outputs of first , second, and third switches are connected to device output. EFFECT: extended linear zone of control signals. 1 cl, 1 tbl
