Abstract
One embodiment of an equalizer circuit has an FIR filterin the asynchronously oversampled domain with a filter coefficient adaptation module that adapts the filter coefficients to the transfer function of a data read channel. Applications include tape drives, drives for optical and magnetic discs as well as receivers. The filter adaptation is performed on the basis of an error signal delivered by a slicerwhich operates on synchronous samples after timing recovery and sample reconstruction.
