Abstract
An encoder/decoder is provided having two random bit generators which are cross-coupled in the Encoding mode with the data signal being directed to the input of each random bit generator. The data signal is also logically combined with the output of each random bit generator. In the Decoding mode the random bit generators are connected in a feedback configuration and the to-be-decoded signal is directed to the input of each random bit generator. The to-be-decoded signal is also logically combined with the output of each random bit generator to provide the decoded signal.
