**Gain Margin**

**08/27/17**

*“What is the margin of stability for a gain Bode Plot?”*

One of the most useful features of a Bode Plot is the ability to find the stability of a system. One way to do that is to find the frequency at which the phase shift becomes 180 degrees, get the amplitude of the gain at the point, and then make a **gain margin** extending out to both sides equal to the magnitude of 1/|Amplitude value|, such that anything within that range will be stable.
