Abstract
An improved Manchester code receiver is disclosed which samples the received signal and subtracts from that sample a previous sample of the received signal delayed by a half-bit time interval. A timing extractor selects sample timing from the central zero crossing of the received signal. The sample time is selected to be a quarter-bit time after the zero crossing time of the received signal.
