Abstract
The author highlights the unity negative feedback root locus of a loop gain having two real poles lying along the real axis to the right of two real zeros. He demonstrates that the complex portion of the root locus (of the closed-loop negative feedback system) is a circle. He locates the center and computes the radius of the circle, and illuminates the stability of the closed-loop system
