Abstract
A data recovery apparatus applied to a receiving device. The receiving device include an interface, an equalizer, a sampling unit, and an analyzing unit. The method of the present invention includes steps of the interface unit receiving an input signal, and the equalizer equalizing the input signal. Then the sampling unit sampling the equalized input signal. the analyzing unit analyzing and statistical calculating the sampled and equalized digital image signal, generating a statistically calculation results, and adjusting parameters of the equalizer according to the statistical calculation results. Therefore, when determining whether the parameters of the equalizer occurs the predetermined effort, changing the adjusting of parameters of the equalizer in the direction.
