ABSTRACT:
A circuit, method and computer program product wherein a nonlinear signal outputted from a nonlinear circuit is nonlinearly processed in two steps using a main circuit and an assistant circuit. The main circuit performs a first relatively rough nonlinear process (main correction), and the assistant circuit performs fine a second adjustment (sub-correction) process on the nonlinearly-processed signal resulting from the first process.
