An analog equalizer (613 and 614) adaptively equalizes an input analog
signal affected with intersymbol interference ("ISI"), or an intermediate
analog signal generated therefrom, to produce a filtered partially
equalized analog signal with reduced ISI. An analog-to-digital converter
(210) converts the filtered analog signal, or an intermediate analog
signal generated therefrom, into an initial digital signal. A digital
equalizer (212) adaptively equalizes the initial digital signal, or an
intermediate digital signal generated therefrom, to produce an equalized
digital signal as a stream of equalized digital values with further
reduced ISI. An output decoder (605) decodes the equalized digital
values, or intermediate digital values generated therefrom, into a stream
of symbols. Equalization control circuitry (213, 214, and 217) adjusts
equalization filter characteristics of the equalizers such that
adjustments of the filter characteristics of the analog equalizer depend
adaptively on adaptive adjustments of the filter characteristics of the
digital equalizer.
