Abstract
An active or translating device having distortion is associated with a controllable predistortion circuit or linearizer. A filter sampler arrangement samples the desired fundamental-frequency signal and its second harmonic. A control circuit forms the ratio of the amplitude of the second harmonic divided by the amplitude of the fundamental-frequency signal, and controls the linearizer to minimize the ratio.
