Consider a unity negative feedback system in Figure 6.27 with loop transfer function where

K L(s) = Ge(s)G(s) = (1+0.5s) (1+0.5s + 0.25s)* Determine the value

K L(s) = Ge(s)G(s) = (1+0.5s) (1+0.5s + 0.25s)* Determine the value of K for which the closed-loop system is marginally stable. a. K = 10 b. K-3 c. The system is unstable for all K d. The system is stable for all K
