    摘要: A digital delaying device for delaying an input signal includes a ring oscillator, a calibration unit, and at least one delay number calculation unit and delay channel. The ring oscillator includes loop-connected delay cells for outputting an oscillation clock. The calibration unit receives a reference clock and the oscillation clock and calculates a pulse number of the oscillation clock corresponding to each reference clock period. The pulse number serves as a period reference pulse number. The calculation unit receives the pulse number and a signal delay value, calculates a signal delay number corresponding to the signal delay value according to the pulse number, and outputs a selection signal. The delay channel includes a multiplexer and cascaded delay cells, which receives an input signal and generates delay signals with different delay timings. The multiplexer selects and outputs one of the delay signals as an output signal according to the selection signal.

    摘要: A data processing system is disclosed. The system includes a processor, a transformer, a first memory buffer, a second memory buffer, a first filter, and a second filter. An obtained transmission signal symbol is first transformed to first data. The first memory buffer stores the first data. The processor obtains peak data based on the first data according to a predetermined threshold. The transformer transforms the peak data to second data and stores the second data in the second memory buffer. The first filter filters the second data to determine reserved data of the second data and removes the reserved data from the second data to generate third data. The transformer transforms the third data to fourth data and stores the fourth data in the second memory buffer. The processor merges the first and fourth data to generate fifth data. The second filter filters the fifth data based on the transmission signal symbol and a previously obtained transmission signal symbol.

    摘要: A modulation method for symbols in a frame of a compact disc includes the steps of receiving a plurality of data words, modulating each data word into a code word of a corresponding data symbol, and providing a plurality of combinations of potential merge bits to be inserted between successive symbols of the frame. At least one combination of candidate merge bits is generated according to the plurality of combinations of potential merge bits, a data symbol immediately preceding the location of the candidate merge bits, and a data symbol immediately succeeding the location of the candidate merge bits. The combination of candidate merge bits which minimizes (optimizes) the absolute cumulative DSV is selected when a subsequent group of possible combinations of candidate merge bits is detected or after a predetermined delay, and the selected combination of candidate merge bits is inserted between the two successive data symbols.
