摘要:
A digital signal reproducing circuit for correcting phase errors of digital signals, and for synchronizing a bit synchronizing clock to the digital signal, including at least a PLL circuit connected to a wave-shaping circuit, a pattern detector connected to the PLL circuit for detecting the specified signal patterns of the digital signal, and a circuit for detecting the phase errors of the inputted digital signals and correcting properly the digital signals after the specified signal pattern are detected by the pattern detector.
