Abstract
The invention relates to an electronic circuit for decoding a read signal from an optical storage medium, the electronic circuit comprising a limit equalizer for amplification of high frequency read signal components without substantially increasing inter-symbol interference, a Viterbi detector being coupled to an output of the limit equalizer for providing the decoded read signal, a coefficient adaptation circuit for tuning the limit equalizer to a partial response target.
