Abstract
A predistortion error signal, corresponding to the third harmonic of an input signal, is generated by obtaining the absolute value of the input signal and multiplying it by the input signal of given sign to provide the square of the latter times the sign of the input signal. The squared signal then is multiplied by the absolute value of the input signal again to provide the desired cube of the input signal.
