(20 pointw) Bode plot. 100 50 Magnitude (dB) -50 -100 -150 -90 -135 Phase (deg) -180 -225 1 102 103 -270 10-1 10° 10' 102 Frequency (rad/s) For parts (a) through (d), show your answers on the plot and estimate the numbers as best you can. . (a) Find the frequency of the gain crossover. Find the phase margin. (b) Find the frequency of the phase crossover. Find the gain margin. (c) Is the closed loop system stable? Why or why not? (d) Assume that the above plot has loop gain K=1. What value of K would increase the phase margin to 45°. Estimate numbers from the plot as best you can, and show your work.
