nonlinear distortion results in the generation of frequencies that are not present in the input.

nonlinear distortion results in the generation of frequencies that are not present in the input. if the dynamic curve can be represented byic= G1ib + G2(ib^2), and if the input signal is given byib= I1 cos w1t + I2 cos w2tshow that the output will contain a dc term and sinusoidal terms of frequency w1, w2,2w1, 2w2, w1 +w2, w1-w2.
