เนื้อหาย่อ : Features The main objectives of the second edition of this book remain the same as in the first edition--to present circuit analysis in a manner that is clearer, more interesting, and easier to understand than earlier texts. This objective is achieved in the following ways: A course in circuit analysis is perhaps the first exposure students have to electrical engineering. We have included several features to help students feel at home with the subject. Each chapter opens with either historical sketches of some electrical engineering pioneers to be mentioned in the chapter or a career talk on a subdiscipline of electrical engineering. This is followed by an introduction that links the chapter with the previous chapters and states the chapter objectives. The chapter ends with a summary of the key points and formulas. o Problem solving is discussed in Chapter I to promote sound, step-by-step problem-solving practices. A bookmark is included with each copy of the book to remind students of the solution steps (and to mark their place). ㆍ All principles are presented in a lucid, logical, step-by-step manner. As much as possible, we avoid wordiness and giving too much detail that could hide concepts and impede overall understanding of the material. ㆍ Important formulas are boxed as a means of helping students sort out what is essential from what is not. Also, to ensure that students clearly get the gist of the matter, key terms are defined and highlighted. Marginal notes are used as a pedagogical aid. They serve multiple uses such as hints, cross-references, more exposition, warnings, reminders not to make some particular common mistakes, and problem-solving insights. Thoroughly worked examples are liberally given at the end of every section. The examples are regarded as part of the text and are clearly explained without asking the reader to fill in missing steps. Thoroughly worked examples give students a good understanding of the solution and the confidence to solve problems themselves. Some of the problems are solved in two or three ways to facilitate an understanding and comparison of different approaches. To give students practice opportunity, each illustrative example is immediately followed by a practice problem with the answer. The students can follow the example step by step to solve the practice problem without flipping pages or looking at the end of the book for answers. The practice problem is also intended to test if students understand the preceding example. It will reinforce their grasp of the material before they move on to the next section. ㆍ The last section in each chapter is devoted to application aspects of the concepts covered in the chapter. The material covered in the chapter is applied to at least one or two practical problems or devices. This helps the students see how the concepts are applied to real-life situations. ㆍ Ten review questions in the form of multiple-choice objective items are provided at the end of each chapter with answers. The review questions are intended to cover the little "ticks" which the examples and end-of-chapter problems may not cover. They serve as a self-test device and help students determine how well they have mastered the chapter. ㆍ The end-of-chapter homework problems (as well as the solutions available at the website for instructors only) have been thoroughly checked for accuracy. There are approximately 25 percent new problems in this edition. ㆍ In recognition of the requirement by ABET (Accreditation Board for Engineering and Technology) on integrating computer tools, the use of PSpice is encouraged in a student-friendly manner. Since the Windows version of PSpice is becoming popular, it is used instead of the MS-DOS version of PSpice. PSpice is covered early in the text so that students can become familiar and use it throughout the text. Appendix D serves as a tutorial on PSpice for Windows. The operational amplifier (op amp) as a basic element is introduced early in the text. ㆍ To ease the transition between the circuit course and signals and systems courses, Fourier and Laplace transforms are covered lucidly and thoroughly.
