A unity feedback system has open-loop transfer function
The gain margin and phase margin are
  • a)
    -3.52 dB, -168.50
  • b)
    -3.52 dB, 11.60  
  • c)
    3.52 dB, -168.50  
  • d)
    3.52 dB, 11.60    
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A unity feedback system has open-loop transfer functionThe gain margin...

∠GH(jω) = -90°- tan-1 ω- tan-1 2ω ,
At unit gain ω1 = 0.57 rad/sec,
Phase at this frequency is ∠GH(jω1) = -90°- tan-1 0.57 -tan-1 2(0.57) = -168.42°
Phase margin = -168.420+180° = 11.6°
Note that system is stable. So gain margin and phase margin are positive value. Hence only possible option is (D).
