For the control system in the given figure, the value of K for critical damping is
Answer: Option
Explanation:
since ζ = 1, ωn = 3.5 Hence 2 + 2k = 3.52 = 12.25 or K = 5.125 .
42.
Bode magnitude plot is drawn between
Answer: Option
Explanation:
Frequency is plotted on log scale and magnitude is taken in dB.
43.
For the system in the given figure, 
none of the above
Answer: Option

For inner loop we have transfer function = 
Then 
= 
.
44.
In the given figure, if R = XC, voltage gain is
Answer: Option
Explanation:
If R = XC, V0 = 0.5 Vi Hence gain is -3 dB.
