ABSTRACT:
A digital data reproducing system which carries out quantization by the frequency over the transmission rate with respect to waveform distortion created by a group delay caused by ghosts and repeaters or the like when digital information signals are received so as to thereby perform waveform equalization, and which carries out phase correction to thereby enable data reproduction about equivalent to that quantized by an ideal sampling timing, thus realizing entire digitization of the data reproducing system.
