ABSTRACT:
A distortion in an amplified signal obtained by amplifying a first input signal, is compensated for by applying a correction factor to the first input signal. The correction factor is updated based on the first input signal and the amplified signal. Updating the correction factor is prohibited when a value of the first input signal is same as a value of a second input signal among a plurality of input signals input previous to the first input signal.
