ABSTRACT:
Apparatus in a receiver for adaptively adjusting the receiver response to changing signal conditions includes a shift register for serially loading signal and having parallel output taps for providing a plurality of signal samples in parallel. Matrix circuitry, coupled to the output taps, is arranged to provide the signal samples in a predetermined order to facilitate forming sums of products of such signal samples.
