摘要:
A digital data recovery system for converting a suboptimal signal into a converted signal that closely approximates an original signal includes a first data filter, a first interpolator and a second interpolator. The first data filter filters the suboptimal signal to generate a first filtered signal. The first interpolator receives the first filtered signal and generates a first interpolated signal. Substantially concurrently, the second interpolator receives the suboptimal signal and generates a second interpolated signal. The digital data recovery system may further comprise a second data filter that receives the second interpolated signal and generates a second filtered signal. Further, the first data filter can include a set of first coefficients and the second data filter can include a set of second coefficients. Moreover, the second coefficients can be updated and subsequently transformed in order to update the first coefficients.
