Using a Nichols chart, determine the gain and phase margin of the system in Figure 10.38 with loop gain transfer function

a. G.M. L(s) = Ge(s)G(s) 20.4 dB, P.M. = 58.1 b. G.M.

a. G.M. L(s) = Ge(s)G(s) 20.4 dB, P.M. = 58.1 b. G.M. = dB, P.M. = 47 c. G.M. 6 dB, P.M. = 45 d. G.M. = 0 dB, P.M. = 23 8s + 1 s(s+2s+4)
