NRZ Digital data recovery

摘要

A clock signal required for demodulation of a received NRZ digital data stream is generated by comparing transition data for the received NRZ digital data stream to a clock signal which has a period equal to the bit period of the NRZ digital data stream. The results of the comparison is utilized to shift the clock signal in such a manner that the clock signal will be synchronized with the received NRZ digital data stream so as to provide a clock signal which may be utilized to demodulate the received NRZ digital data.
