<P>PROBLEM TO BE SOLVED: To provide a data recovery method and a data recovery device capable of suppressing demodulation error occurrence even when a jitter of an input serial signal is large. <P>SOLUTION: A data recovery method which uses a data recovery device to recover data represented by an input serial signal includes: an equalizing step (S1) of equalizing the serial signal; an oversampling step (S2) of oversampling the serial signal equalized by the equalizing step; an evaluation step (S3) of calculating a pattern length of the serial signal equalized by the equalizing step on the basis of the oversampled data acquired by the oversampling step and evaluating the processing result of the equalizing step according to the calculated pattern length; and an equalization amount adjustment step (S4) of adjusting an equalization amount of the equalizing step on the basis of the evaluation result of the evaluation step. <P>COPYRIGHT: (C)2013,JPO&INPIT |
