If D1, D2, D3, D4 are the distortion produced by second, third, fourth, fifth respectively (others are insignificant). Then total harmonic distortion is __________(a) √(D1^2+D2^2+D3^2+D4^2)(b) √(D1^2+D3^2)(c) √(D2^2+D4^2)(d) √(D1^2+D2^2)The question was posed to me by my college professor while I was bunking the class.Question is taken from Distortion in Amplifier in division Power Amplifier of Analog Circuits |
