Digital signal regenerator.

摘要

A digital signal regenerator responsive to a data bit stream (1) having a predetermined bit rate for generating a retimed data bit stream includes a transition detector and a pulse generator (10) responsive to the data bit stream for detecting transition positions between two different states of the data bit stream and for generating width variable pulses at the transition positions, a filter (20) responsive to the width variable pulses for extracting a timing wave of the data bit stream, a clock pulse generator (30) responsive to the timing wave for generating a clock pulse sequence, and a discriminator (40) responsive to the clock pulse sequence for discriminating the levels "1" and "0" of the data bit sequence to generate the retimed data bit stream.
