A voltage amplifier ideally should have the input-output relationship of V₀ = 100vi but in practice the relationship is V₀ = Vi (98 + 2Vi).

Calculate the %age second harmonic distortion presents in the amplifiers output for a sinusoidal input of 10mV r.m.s.

Hi everyone! Can anyone please confirm that the following is correct or at least somewhere near?

Vo = 98vi + 2vi²

Vo = 98 x 10 + 2 x 10²

Vo = 1180mV

%age of Second Harmonic Distortion = Amplitude of Second Harmonic / Amplitude of fundamental x 100

%age of Second Harmonic Distortion = 200/1180 x 100 = 16.95%
