Number: 326/11
Name: Electronic digital logic circuitry > Reliability > Redundant > Voter circuit (e.g., majority logic, etc.)
Description: Subject matter including a logic level switching circuit having a plurality of inputs which actuate the duplicate logic stage whenever one of the following conditions is obtained (a) More than half, but less than all inputs are "fault" (i.e., majority); (b) More than one, but less than half of all the inputs are "fault" (i.e., minority); or (c) Various predetermined combinations, together or in predetermined sequence, of the inputs are "fault" (i.e., weighted).
