Abstract:
1. A transmission line equalizer, comprising: a plurality of signal paths connected in parallel between an equalizer input signal and an output amplifier, each signal path having a network implementing a specific frequency dependent response, each signal path implementing current gain amplification with one or more of the signal paths having a variable gain programmed through a time invariant, DC programming signal, and one or more of the signal paths implementing linear-to-nonlinear signal transformations and compensating nonlinear-to-linear signal transformations to generate linearized output signals at the one or more signal paths; and the output amplifier configured to sum the output signals from the plurality of signal paths and to generate an equalized output signal, wherein the gain of the one or more signal paths is varied to establish the relative proportions of the output signals generated by each signal path and summed at the output amplifier.
