A voltage amplifier ideally should have the input-output relationship of
vo = 100vi but in practice the relationship is vo = vi(98 + 2vi).
Calculate the %age second harmonic distortion present in the amplifier’s
output for a sinusoidal input of 10 mV r.m.s
% harmonic distortion = amplitude of nth harmonic / amplitude of fundnamental
fundnamental
98*0.01=0.98 v
harmonic
2*2*0.01^2 = 0.004 v%= 0.0408No frequency has been given. So in am unsure.
All help is appreciated.
Thanks
