Consider the total harmonic distortion of a closed loop system is 5%.D

1.	Consider the total harmonic distortion of a closed loop system is 5%.Distortion without feedback is 10%. Calculate the sensitivity of closed loop system.(a) 0.5(b) 0.2(c) 0.6(d) 0.1The question was asked by my college professor while I was bunking the class.This question is from Effects of Feedback topic in division General and Feedback Amplifiers of Analog Circuits
Answer» Correct CHOICE is (a) 0.5 To explain I WOULD say: DHF = DH/1+Aβ 1 + Aβ = DH/DHF = 10/5 = 2 Sensitivity = \(\frac{1}{2}\) = 0.5.
