FIELD: electricity.
SUBSTANCE: device for signal processing for processing of an input signal comprises an amplifier, a step-down converter with the possibility to multiply the version of the processed signal by the version of the amplified signal, an adaptive pre-distorter made with an additional capability to adapt the characteristic of the preliminary distortion on the basis of the first signal with step-down frequency and the second signal with the step-down frequency.
EFFECT: preliminary pre-distortion for efficient processing of an inlet signal, compensation of non-linear effects of an amplifier.
