Shown below are the closed-loop Bode magnitude plots for 4 transfer functions G1, G2, G3, and G4. Answer the following questions below. If multiple systems satisfy the requested property then list them all. If no systems satisfy the desired property then answer “NONE”. (2 Points Each) 30 G -G2 20 2 G 4 10 0 -10 Magnitude (dB) -20 -30 -40 -50 -60 LILUL 103 102 10-1 100 101 102 103 Frequency (rad/s)

(f) Which system is most susceptible to noise in the mid-frequency band 10-1 <w < 101. (g) Which system is least susceptible to noise in the mid-frequency band 10-1 <W < 101. (h) Which system is most susceptible to noise in the high-frequency band 101 SW s 103. (i) Which system is least susceptible to noise in the high-frequency band 101 <w < 103.
