Question

Is phase margin is sufficient to determine close loop stability than gain margin?

Answer 1

the phase difference between and is 180°, and this closed-loop system thus becomes a positive feedback system. This system will continue to amplify its output and become unstable. If a closed-loop system is stable, both the gain margin and the phase margin need to be positive.

Answer 2

Answer:

heya..

2.26, the phase difference between and is 180°, and this closed-loop system thus becomes a positive feedback system. This system will continue to amplify its output and become unstable. If a closed-loop system is stable, both the gain marginand the phase margin need to be positive.

i hope its help u
