Question: Determine whether the closed-loop system in Figure 9.69 is stable or not, given the loop transfer function s+1 = L(s) Ge(s)G(s) == s(4s + 1)

Determine whether the closed-loop system in Figure 9.69 is stable or not, given the loop transfer function

s+1 = L(s) Ge(s)G(s) == s(4s + 1) In addition, if the

s+1 = L(s) Ge(s)G(s) == s(4s + 1) In addition, if the closed-loop system is stable, compute the gain and phase margins. a. Stable, G.M. = 24 dB, P.M. = 2.5 b. Stable, G.M. = 3 dB, P.M. = 24 c. Stable, G.M. = 0 dB, P.M. = 60 d. Unstable
