N2 - The partial-response maximum likelihood (PRML) method requires efficient equalization in order to obtain the desired patterns of ISI before the signal processing of Viterbi decoding is applied. The sampled analog system is the most efficient way to implement the partial response algorithm and it has been mainly implemented by an analog FIR filter. In this paper, various design considerations-gain error offset, system resolution, and the jitter problem for the equalizer-Are presented to incorporate the sampled analog system. Finally, the modified phase detector algorithm for a sampled analog equalizer is proposed.
