Digital signal processing apparatus and methods for modifying frequency response of a signal is described herein. In one aspect, the invention relates to an improved method for stabilizing the LMS adaptation of an FIR filter. In another aspect, the invention relates to a digital equalizer with tap weights that are adapted to move towards some pre-defined tap weight reference, rather than towards zero. In one variation, the digital equalizer is able to provide both signal equalization and automatic gain control.
