Quizplus · Accepted Answer

A system with a gain margin close to unity or a phase margin close to zero is highly oscillatory, indicating it is on the verge of instability. This is because a small gain margin means the system can easily become unstable with a slight increase in gain, and a small phase margin means the system's response can easily oscillate.
