Magnitude of Characteristic Equation for 3 Real Poles

Cuthbert Nyack

Applets show the magnitude and phase of the charactic equation in the complex s plane. Closed loop poles occur where the characteristic equation is zero.
Parameters (8.0, 1.0, 1.0, 1.0, -60.0, 20.0, 20) show the magnitude of the characteristic eqn having zeros at -3 and at ±j3^½.
Parameters (1.0, 3.0, 2.0, 0.3, -60.0, 20.0, 20) show the magnitude of the characteristic eqn having 3 zeros along the real axis.
