Abstract: A signal selection system has input thereto a plurality of redundant input signals (A, B, C, D) having varying values along with signals indicative of the validity of the plurality of input signals, comparison logic (42-52) compares all possible pairwise combinations of the input signals to determine which input signal in each of the input signal pairs has the greater value or to determine if the input signals in each pair have equal values. Selection logic (80) determines which one or more of the values of the input signals from the plurality of valid input signals are to be used to determine the output signal according to a predetermined criterion. The selection logic (80) has a plurality of combinational logic elements arranged to execute predetermined Boolean logic equations in determining which one or more of the values of the input signals from the plurality of valid inputs are to be used to determine the output signal (MID) according to the predetermined selection criterion.
Abstract translation: 一种信号选择系统，其中各种值（A，B，C，D）的多个冗余输入信号与指示多个输入信号的有效性或其他信号的信号一起被引入。 比较逻辑（42-52）比较输入信号对的所有可能组合，以确定每对中的两个输入信号中的哪一个具有最高值，或者确定每对中的信号 具有相同的价值。 选择逻辑（80）根据预定标准确定将使用多个经确认的输入信号中的哪个输入信号值来确定输出信号。 选择逻辑（80）具有多个组合逻辑元件，所述多个组合逻辑元件被布置成执行预定的布尔逻辑方程以确定多个经验证的输入信号中的哪些（多个）输入信号值将是 ）来确定所述预定选择标准的输出信号（MID）。
