<p>A demodulation circuit and a demodulation table of a digital video disk (DVD) reproducing apparatus. The demodulation circuit of a DVD reproducing apparatus for re-constructing data symbols designating a next state of a second state and data symbols designating a next state of a third state by different tables includes a shift register (70) for storing an EFM plus bit stream reproduced from a disk, first and second demodulators (72, 74) for converting a code word of more significant bits of a data symbol supplied to the shift register into 8-bit demodulation data according to a designated next state, a state detector (76) for detecting a next state from the code word of less significant bits of a data symbol supplied to the shift register and generating a state select signal, and a multiplexer (78) for selectively generating one of output signals of the first and second demodulators according to the state select signal. <IMAGE></p> |
