Claim 10:
11. A method comprising:
generating, using a front-end circuit, a filtered signal, wherein generating the filtered signal comprises performing filtering of an incoming signal that includes a stream of data symbols;
generating, using a summing circuit, an equalized signal, wherein generating the equalized signal comprises the summing circuit combining the filtered signal and a feedback signal;
generating, using a sample recovery circuit, a plurality of recovered data symbols by sampling the equalized signal;
generating the feedback signal, using a decision feedback equalization circuit, based on the plurality of recovered data symbols; and
causing adjustment to one or more filters in the front-end circuit, using a logic circuit, based on the plurality of recovered data symbols, wherein the logic circuit comprises a finite state machine, and wherein the method further comprises the finite state machine generating control signals to cause adjustment to one or more resistances and one or more capacitances in the filters of the front-end circuit.
