3. Two feedback systems are shown in Figures 1.a and 1.b. (a) (v) Figure 1: Two feedback systems (a) Evaluate the closed-loop transfer functions \( T_{1} \) and \( T_{2} \) for each system and compare them for \( K_{1}=K_{2}=1 \). (b) Compare the sensitivities of the two systems with respect to the parameter \( K_{1} \) for the nominal values of \( K_{1}=K_{2}=1 \).
