Natural frequencies are roots of characteristic equations. The characteristic equation
of the differential equation in Eqn. 12.1-29 is and its roots are
.
The natural frequencies are coincident at –1 (with RC 1 s) when kis 1. As k
increases from 1, the natural frequencies become complex conjugate numbers with a
negative real part. When kassumes the value of 3, the natural frequencies become +j1
rad/s and –j1 rad/s. As k increases above 3, the natural frequencies become complex
conjugate ...
