A nolinear distortion results in the generation of frequencies in the output that are not present in the input. If the dynamic curve can be represented by ic = Aib + B(ib^2), and if the input signal is given by ib= I1 cos w1t + I2 cos W2t show that the output will contain a dc term and sinusodial terms of frequency w1,w2,2w1,w1 + w2, and w1 - w2.
