Q. For a second-order system, what does a damping ratio of 0.5 indicate?
A.
Underdamped response
B.
Critically damped response
C.
Overdamped response
D.
Stable response
Solution
A damping ratio of less than 1 (0.5 in this case) indicates an underdamped response, characterized by oscillations.
Q. What is the phase margin if the gain crossover frequency is at 45 degrees?
A.
0 degrees
B.
45 degrees
C.
90 degrees
D.
135 degrees
Solution
The phase margin is calculated as 180 degrees minus the phase at the gain crossover frequency. If the phase is -135 degrees, the phase margin is 45 degrees.
