ABSTRACT:
An adaptive equalizer for a demodulator includes a filter that generates a filter output signal in response to an information signal according to a transfer function for the filter. The adaptive equalizer includes means for adjusting the transfer function in response to an indication of error in the filter output signal, and means for switching among a set of differing determinations of the indication of error. Switching among the differing determinations may be based upon a variety of indications of the progress of adaptation in the equalizer.
