A treatment of topics in the field of electric networks (or circuits) which are considered as a foundation in electrical engineering and occur at either the beginning or intermediate level. Contains material on the Nyquist criterion. Gives Tellegan's theorem, and the Gauss elimination method. Includes expanded coverage of Thevenin's and Norton's theorems, the Routh-Hurwitz criterion, and Fourier transforms. Problems and suggested digital computer exercises at the end of each chapter.
