P8.27 A unity feedback system has the loop transfer function L(s) = Ge(s)G(s) - K(s + 50) s + 10s +25 Sketch the Bode plot of the loop transfer function and indicate how the magnitude 20 log| L(jw)| plot varies as K varies. Develop a table for K = 0.75, 2, and 10, and for each K determine the crossover fre- quency (w, for 20 log| L(jw)| = 0 dB), the magnitude at low frequency (20 log| L(jw) | for w < < 1), and for the closed-loop system determine the bandwidth for each K.
