摘要： Regeneration of a Manchester coded data stream is improved by a system for distinguishing which data signal transitions are bit center and which are bit end transitions. Using a monostable flip-flop with associated phasing and timing circuits including a feedback circuit from the clock output itself, the edge transitions are masked to allow only the center transitions to be passed and then used to create the timing pulses. A system for avoiding lockup of the apparatus on an erroneous initial pulse is also described.
