ABSTRACT:
A system having a plurality of redundant channels operating in tight synchronism wherein input information received in one or more of said channels is distributed to all the other channels. The received information in each channel is retransmitted to suitable voter circuitry in each channel so as to provide one or more voted outputs in each channel based on the distributed and retransmitted information from all the channels. The voted outputs from all unfailed channels are substantially identical and the voted output from a failed channel will not be identical to that of the unfailed channels.
