Abstract
An apparatus comprises a summer suitable for subtracting a filtered feedback signal from an input; a symbol decision device suitable for receiving an output from the summer; a feedback filter suitable for filtering an output from the symbol decision device and for sending the filtered feedback signal to the summer, the feedback filter comprising an adjustable swing amplifier and an adjustable pole filter; and an adaptation algorithm suitable for simultaneously adapting both a pole setting and a swing setting based upon a least mean squared error criteria. The summer, the symbol decision device, and the feedback filter form a feedback circuit utilized to reconstruct an electrical signal distorted during transmission.
