Abstract
A method to encode two digital data signals is disclosed. Each of the digital signals is characterized by a bit stream. An N bit block from the first signal is mapped to a unique M bit third signal where M is greater than N. Further, the number of "0's" in the M bit third signal is less than M/2. The M bit third signal is transmitted in the event a bit from the second signal is 0, whereas the complement of the M bit third signal is transmitted in the event a bit from the second signal is 1.
