An adaptive equalizer processes an input signal that includes noise, pre-cursor intersymbol interference, and post-cursor intersymbol interference. The adaptive equalizer includes a feedforward filter which reduces the pre-cursor intersymbol interference and whitens the noise, a feedback filter which detects the post-cursor intersymbol interference in a signal that corresponds to the input signal, and circuitry which removes the detected post-cursor intersymbol interference from the input signal. The feedforward filter includes separate first and second coefficients. The first coefficients reduce the pre-cursor intersymbol interference and the second coefficients whiten the noise.
