Gain Margin:<br />
The gain margin is the number of dB that |G(jv ′ | is<br />
below 0 dB at the phase crossover frequency (phase<br />
angle φ of G(jv ′ ) = 180 ◦ . It can also be defined as the<br />
amount of the system gain that can be increase before<br />
the closed loop system becomes unstable.<br />
Phase Margin: The phase margin is the number of degrees the<br />
phase of |G(jv ′ | is above −180 ◦ at the gain crossover<br />
frequency (|G(jv ′ | = 1. It can also be defined as the<br />
angle where the phase can be increased before the<br />
closed loop system becomes unstable<br />
