Consider a closed-loop system with negative feedback. The feedback transfer function is H(s) = and the forward path transfer function is G(s) = 2+s+1 K. with K being a positive real number. I+s+ What is the effect of modifying the value of K? o The closed-loop system is marginally stable if K-1, stable if K<1, and unstable if K>1 • The closed-loop system is unstable if K<1 while stable if K>1 o The closed-loop system is stable if K<1, and unstable if K>1 but never marginally stable. The closed-loop system is marginally stable if K-D1, stable if K>1, and unstable if K<1
