Abstract
There is provided a digital signal reproducing apparatus comprising: a binarization circuit to binarize a signal which was read out of a recording medium or a transmitted signal; first and second pulse generators to generate pulses which are respectively synchronized with leading and trailing edges of a binary signal which was binarized by the binarization circuit; 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 NRZI coding method. Each pulse generator has a PLL circuit. 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.
