Digital signal reproducing apparatus.

摘要

There is provided a digital signal reproducing apparatus comprising: a binarization circuit (5) to binarize a signal which was read out of a recording medium or a transmitted signal; first and second pulse generators (15, 16) to generate pulses which are respectively synchronized with leading and trailing edges of a binary signal which was binarized by the binarization circuit (5); and first and second signal generators to generate first and second position signals indicative of the positions of the leading and trailing edges synchronously with the first and second sync pulses which are generated from the first and second pulse generators. The binary signal is a signal of the NRZ coding system. Each pulse generator has a PLL circuit (17, 18). With the apparatus, the signal can be accurately reproduced irrespective of the recording density by compensating the phase difference between the leading and trailing edges of the binary signal.
