1. An apparatus for providing verified communication, comprising: a transmitter including: input terminals to receive a data word, an encoder configured to encode the data word to create an encoded word different from the data word, and output terminals configured to transmit the data word and the encoded word; and, a receiver coupled to the transmitter and including: input terminals to receive the data word as a received word and the encoded word, a decoder configured to decode the encoded word to create a decoded word, and a comparator configured to compare the received word and the decoded word to create a select signal, and a selector responsive to the select signal and configured to select the received data word or the decoded word based at least in part on the select signal; wherein the transmitter is configured to simultaneously transmit the data word and the encoded word; and wherein the receiver is configured to simultaneously receive the data word and the encoded word; a first signal detector coupled to a first communications channel including a set of received words; a second signal detector coupled to a second communications channel including a set of the encoded words; wherein, if the first communications channel is not available, the first signal detector notifies the comparator which instructs the selector to choose the set of encoded words from the second communications channel; and, wherein, if the second communications channel is not available, the second signal detector notifies the comparator which instructs the selector to choose the set of received words from the first communications channel.
7. The apparatus of claim 1 , wherein: the comparator is configured to compare the bits in the received word with those in the decoded word and to select the valid bits in each word to recreate the data word.
