Abstract: PURPOSE: An apparatus for compensating for selective disturbance in the event of playback of an optical recording medium and a 3T correcting method are provided to correct a tilt or asymmetry generated on the optical recording medium by selectively using an equalizer and a T-correction circuit. CONSTITUTION: An apparatus for compensating for selective disturbance in the event of playback of an optical recording medium includes a DC offset removing means(210), a switch(230), the first and second signal processors(240,250). The DC offset removing means for extracting and removing a DC offset from a signal read from the optical recording medium. The switch judges if distortion due to asymmetry contained in the signal from which the DC offset was removed is more than a predetermined reference value or not. The first signal processor is selected when the distortion is judged to be less than the reference value so as to equalize the signal from which the offset was eliminated. The second signal processor is selected when the distortion is judged to be higher than the reference value, to receive the signal output from the DC offset removing means so as to correct the symmetry or accept the output signal of the first signal processor when the first signal processor is selected to correct asymmetry contained in the signal.

Abstract: PURPOSE: A jitter detecting apparatus is provided to detect a jitter amount using signals existing at two sampling points around an edge, from an analog-to-digital converted signal. CONSTITUTION: An edge detecting portion(200) judges symbol variation of signals at two successive sampling points from a DC offset-eliminated input signal, and outputs a before-symbol-variation signal and an after-symbol-variation signal as first and second edge signals, respectively. A comparator portion(210) compares the first and second edge signals from the edge detecting portion(200) and outputs any one of the first and second edge signals having a relatively small absolute value. A calculation portion(220) outputs a jitter value by dividing the relatively small absolute value from the comparator portion(210) by a sum of absolute values of the first and second edge signals.

Abstract: PURPOSE: A frequency detection device in a digital phase locked loop has a high resolution at a low clock frequency in digital phase locked loop. CONSTITUTION: In a frequency detection device, a look-up table memory predicts a center data of {A(N-1),A(N)} at a zero-crossing point by using a sampling data(A(N-1)), addition value(SUM), and a multiplication value(MUL), uses the predicted center data as a sampling data of a double clock signal, and makes the counting control data as a look-up table. Arithmetic part performs addition operation and a division operation about A(N-1) and A(N). A code determining parts(801,802,803) determine a code of the addition value(SUM), the multiplication value(MUL) and the sampling data A(N-1). A mapping address generators(804,805,806,807,808) generate a mapping address of the loop-up table by using a code determination result of the addition value(SUM), the multiplication value(MUL) and the sampling data A(N-1). A counting controller(605) reads the counting control data stored in the loop-up table memory by the mapping address, and operates the up/down counter. A maximum value holding part(404) holds a maximum value of the up/down counter in a period of one frame over, and outputs the maximum value. Thereby, a precise frequency detection is achieved.
