A digital data recovery system (14) for converting a suboptimal signal (18) into a converted signal (20) that closely approximates an original signal (16) includes a first data filter (22), a first interpolator (26) and a second interpolator (36). The first data filter (22) filters the suboptimal signal (18) to generate a first filtered signal (48). The first interpolator (26) receives the first filtered signal (48) and generates a first interpolated signal (52). Substantially concurrently, the second interpolator (36) receives the suboptimal signal (18) and generates a second interpolated signal (64). The digital data recovery system (14) may further comprise a second data filter (38) that receives the second interpolated signal (64) and generates a second filtered signal (66). Further, the first data filter (22) can include a set of first coefficients (50) and the second data filter (38) can include a set of second coefficients (68). Moreover, the second coefficients (68) can be updated and subsequently transformed in order to update the first coefficients (50). |
