Claim One:
1. A system, configured to drive a wired load, the system comprising: a frequency-selective analog circuit, including an analog circuit input to receive a digitally pre-distorted signal, and an analog circuit output configured to be coupled to the load; a digital-predistortion (DPD) circuit, including a DPD input and including a DPD output coupled to the analog circuit input, the DPD circuit configured to apply a nonlinear digital predistortion to an input signal received at the DPD input to provide, at the DPD output, the digitally pre-distorted signal to the analog circuit input based on feedback from a signal downstream from the frequency-selective analog circuit; a frequency-selective digital circuit, including a digital circuit input to receive a digital input signal, the digital circuit having a frequency response selected to emulate a frequency response of the frequency-selective analog circuit, and having a digital circuit output coupled to the DPD input; and a frequency selective equalizer circuit, including an equalizer input coupled to the DPD output, and an equalizer output coupled to the analog circuit input.
