MAJORITY ELEMENT Russian patent published in 1999 - IPC

FIELD: electronic equipment. SUBSTANCE: device has three inputs, three subtraction amplifiers, three relays and three gates, which outputs are connected to device output. Device provides analysis of levels of input signals by means of their comparison using subtraction amplifiers in 2 of 3 circuit. Depending on comparison results, relays generate signals for controlling gates, which switch device output to either of two inputs, which signal levels are equal and switch device output from inputs in case of presence of more than one input signal which value differs from real one by intolerant range. EFFECT: increased reliability of hot redundancy equipment. 1 dwg, 2 tbl
