Abstract

1,225,196. Transistor switching circuits. V. Y. AUZIN, and L. A. KATUNINA. 19 July, 1968 [21 July, 1967], No. 34465/68. Heading H3T. A two-out-of-three majority logic circuit comprises four transistors connected sunstantially as shown in the Figure. Resistors R9 and R10 can be relays which will be operated as long as two or three inputs occur at the respective input terminals I, II or III. The circuit, which fails safe on component failure, may be used in triple redundant systems which provide an output if the signal or pulse train from two of the input sources continue.
