In some embodiments, the inventions includes a transmitter including a
cycle encoding circuit to receive a data input signal and to provide a
full cycle encoded signal in response thereto by continuously joining
portions of different encoding signals. Some of the encoding signals have
a different frequency than others of the encoding signals and some of the
encoding signals have a different phase than others of the encoding
signals. Data is represented in data time segments of the full cycle
encoded signal and no data time segment has more than one cycle of an
encoding signal. In some embodiments, a receiver receives the cycle
encoded signal and recovers data of the data input signal.
