Abstract
A device (2) for determining optimal equalizer settings (setE_opt) for an equalizer (1) for equalizing a pulse amplitude modulation signal (L0, L1, L2, L3) comprises an estimator section (21) configured for receiving at least a part of the equalized pulse amplitude modulation signal (L0′, L1′, L2′, L3′) from the equalizer (1), and for receiving an offset signal (offS), and for generating an estimator signal (estS) indicative of a percentage of signal levels of the at least a part of the equalized pulse amplitude modulation signal (L0′, L1′, L2′, L3′) which are larger or smaller than the offset signal (offS). The device comprises a controller (22) configured for receiving the estimator signal (estS), and for generating the offset signal (offS), and for generating equalizer settings (setE) for the equalizer (1), wherein the controller (22) includes an optimizer (221) for determining the optimal equalizer settings (setE_opt) for the equalizer (1) by evaluating the estimator signal (estS) for a range of offset signals (o1, . . . o4) and for a range of equalizer settings (setE0, setE_opt, setE2).
