Hayts Circuit Theory
"Hayts Circuit Theory" is a Korean version of "Engineering Circuit Analysis, 9th edition" by William H, Hayt, Jr. Since the first edition has been published, it has been revised to meet the latest technology trends, and now the revised version 9 has been published. The authors have written for learners who are not lecturers, to learn and enjoy learning independently of the difficulty of technical contents. To do this, each chapter consists of relatively short ones, each one containing one main theme. In order to understand the contents of this book, learners need only basic knowledge on algebra, algebraic equations and calculus, and they have various and appropriate examples and exercises to improve their problem solving abilities.

Meanwhile, the basic version of the 9th edition of the Revised Edition has been maintained as it was in the 8th edition. The contents of the transient analysis section, the frequency response section, and the positive feedback operational amplifier section of Chapter 8 have been revised and supplemented. With the adoption of the free software LTspice as a computer simulation tool, the description of this part has been changed accordingly, and two chapters on Laplace transform and s-domain circuit analysis have been integrated into one chapter.
