A device comprises a variable-gain input amplifier, a low-pass analog filter, a transversal continuous-time analog filter, and two distinct and parallel sampling channels interposed between the transversal analog filter and an RLL-NRZ decoder. The two sampling channels each comprise an analog-to-digital converter and a Viterbi detector arranged in series and operating according to sampling sequences that alternate with one another.
