An encoding method which involves a digital state change (0 to 1 or vice versa) for every bit representation occurring in the middle of the transmitted bit. Useful in local area networks because it is self-clocking. The receiver can develop the data clock from the transmitted data stream. Used in Token Ring and Ethernet systems. Standard Ethernet uses Manchester encoding which results in 10 Mbps throughput at 10 MHz frequency (one-for-one).
