Abstract:
1. An equalizer, for equalizing a first transmission signal on a transmission line, the equalizer comprising: a filter, configured to receive the first transmission signal, to perform a filtering operation on the first transmission signal according to a feedback signal to generate an output signal; a first slicer, coupled to the filter, configured to generate a first sliced signal according to a signal level of the output signal and to adjust an amplitude of the first sliced signal according to an amplitude control signal; a boost control module, coupled to the filter and the first slicer, configured to generate the feedback signal according to the output signal and the first sliced signal; and a control circuit, coupled to the first slicer, configured to receive a second transmission signal on the transmission line and output the amplitude control signal to control the amplitude of the first sliced signal of the first slicer according to an amplitude of the second transmission signal.
