Phase angle and margin
Trying to find the angles of departure and angles of arrival for an equation. In my current problem, I am looking for the angle of departure for
GH=10(s+z)/s^2 (also GH(jw)=10(jw+z)/(jw^2)
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
The s^2 is the pole portion of the equation and it represents 2 poles at the orgin (on the jw axis).
