Patent ID: 8750367

Claim:
A transceiver comprising: an equalizer configured to receive an input signal; a control circuit configured to (i) select a predetermined coefficient, (ii) maintain the predetermined coefficient at a fixed value, and (iii) based on the predetermined coefficient, select a first plurality of coefficients and a second plurality of coefficients, wherein the control circuit is configured to select the predetermined coefficient, at least one of the first plurality of coefficients, and the second plurality of coefficients such that a sum of the predetermined coefficient, the at least one of the first plurality of coefficients, and the second plurality of coefficients is equal to a predetermined value, wherein the control circuit is configured to, while maintaining the predetermined coefficient at the fixed value and while the equalizer is receiving the input signal, adjust a coefficient of one of (i) the first plurality of coefficients, or (ii) the second plurality of coefficients, and wherein the equalizer comprises a first plurality of taps configured to, based on the first plurality of coefficients, filter the input signal to generate a first filtered signal, a unity tap configured to, based on the predetermined coefficient, filter the first filtered signal to generate a second filtered signal, and a second plurality of taps configured to, based on the second plurality of coefficients, filter the second filtered signal to generate a third filtered signal; and an output configured to transmit the third filtered signal.
