Abstract
The Nyquist and the Routh-Hurwitz stability criteria as methods of locating regions of stability of dynamical and electrical systems are described and compared. The superiority of the Routh-Hurwitz method in some applications is demonstrated by two examples, the first a two-loop, three-stage, feedback amplifier of Llewellyn, and the second a multiloop servo system.
