ABSTRACT:
An apparatus for equalizing input signals including high and low frequency component signals received at an locus includes: (a) a first signal amplifying circuit coupled with the input locus, blocking the low frequency component signals and amplifying the high frequency component signals by a first gain to present a first amplified signal; the first gain is established by a relationship between at least two resistance elements in the first signal amplifying circuit; (b) a second signal amplifying circuit coupled with the input locus amplifying the input signal by a second gain to present a second amplified signal; and (c) a combining circuit combining the first amplified signal and the second amplified signal to present an output signal representative of the input signal at an output locus.
