เนื้อหาย่อ : The central theme of Introduction to Electric Circuits is the concept that electric circuits are part of the basic fabric of modern technology. Given this theme, we endeavor to show how the analysis and design of electric circuits are inseparably intertwined with the ability of the engineer to design complex electronic. communication, computer, and control systems as well as consumer products. APPROACH & ORGANIZATION This book is designed for a one- to three-term course in electric cireuits or lincar cireuit analysis and is structured for maximum fexibilisy. The fowchart in Figure | demonstrates alternative chapter organizations that can accommodate different course outlines without disrupting continuity. The prescntation is geared to readers who are being exposed to the basie concepts of electric circuits for the first time, and the scope of the work is broad. Students should come to the course with the basic knowledge of differential and integral calculus. This book endeavors to prepare the reader to solve realistic problems involving electric circuits. Thus, circuits are shown to be the results of real inventions and the answers to real needs in industry. the office, and the home. Although the tools of electric circuit analysis may be partially abstract, electric circuits are the building blocks of modern society. The analysis and design of electric circuits are critical skills for all engincers. WHAT'S NEW IN THE 8TH EDITION Increased use of PSpice " and MATLAB Significantly more attention has been given to using PSpice and MATLAB to solve cireuits problems. It starts with two new appendixes, one introducing PSpice and the other introducing MATLAB. These appendixes briefty describe the capabilities of the programes and illustrate the steps needed to get started using them. Next, PSpice and MATLAB are used throughout the text to solve various circuit analysis and design problems. For example, PSpice is used in Chapter 5 to find a Thevenin equivalent circuit and in Chapter 1 5 to represent cireuit inputs and outputs as Fourier series. MATLAB is frequently used to obtain plots of eircuit inputs and outputs that help us see what our ecquations are telling us. MATLAB also helps us with some long and tedious arithmetic. For example, in Chapter 10, MATLAB helps us do the
