Transform Circuit Analysis for Engineering and Technology

This revised edition is written for an advanced undergraduate circuit analysis course in an applied engineering or an upper-division engineering technology curriculum. This book can also serve as a reference for engineers and technologists. The first four chapters are devoted to time-domain considerations. Chapter 5 through 8 present transform-domain considerations. Chapter 9 deals with Fourier analysis and the concept of spectrum. Both the Fourier series and the Fourier transform are covered. Chapter 10 provides an introduction to discrete-time systems. The Electronics Workbench trade; (EWB) examples found in the last section of most chapters have been modified to work with Multisim, the newest version of EWB. The text also contains a number of MATLAB trade; examples. As in the case of Multisim, coverage is optional and is not a prerequisite to other topics within the text. Appendix E provides a brief introduction to MATLAB to familiarize readers with the program the program. A free Instructor's Manual (ISBN0-13-060250-7) is available to instructors.

As in the case of the first four editions, this fifth edition was designed for an advanced undergraduate circuit analysis course in an applied engineering curriculum or in an upper-division engineering technology curriculum. The book could also serve as a self-study reference for engineers and technologists. The reader should be familiar, with the fundamentals of differential and integral calculus and with basic do circuit analysis techniques. It is anticipated that most readers will also be familiar with steady-state ac circuit theory. However, the latter condition is not a necessity, since a major portion of the book may be mastered without a background in ac circuits. The first four chapters are devoted to time-domain considerations. Chapter 1 is an introduction to the general philosophy of the book. The fundamentals of waveform analysis are presented in Chapter 2. The reader should find that his or her knowledge of differentiation and integration will be strengthened after mastering this chapter, particularly in regard to graphical techniques. The voltage-current relationships for each of the basic circuit elements are explained in Chapter 3 and developed fully in Chapter 4. The next four chapters are devoted to transform-domain considerations. Following a detailed development of the Laplace transform and inverse transform in Chapter 5, the use of transform techniques in obtaining complete circuit responses is presented in Chapter 6. In Chapter 7, the emphasis shifts to the system concepts of circuit theory. Among the topics considered are transfer functions, impedance functions, convolution, and stability. In Chapter 8, sinusoidal steady-state techniques are developed and compared with Laplace transform techniques. The frequency response concept is developed, and the use of pole-zero methods for obtaining frequency response plots is explored. Chapter 9 deals with Fourier analysis and the concept of a spectrum. Both the Fourier series and the Fourier transform are covered. Chapter 10 provides an introduction to discrete-time systems. Topics covered include sampled signals, the sampling theorem, difference equations, and the z-transform. This chapter represents a modern and timely supplement to the continuous-time material predominant through the remainder of the book. Among the topics presented in the appendices are complex algebra and several proofs of transform theorems. These topics may be considered at the discretion of the instructor whenever possible. Depending on the nature of the course and the background of the students, there is reasonable latitude available on the depth and rigor with which the material in this book can be presented. On the one hand, the derivation and formulation of the principles involved can be emphasized. On the other hand, the use of principles as tools for solving and interpreting practical problems can be emphasized, with only casual consideration of the mathematical fine points. Any suitable compromise between these limits should be possible. Multisim and MATLAB The circuit analysis program featured in the previous edition of the text was Electronics Workbench. This program has now evolved into a new product with the name Multisim. The result has been a continued improvement in the product. It served as the basis fir computer-aided circuit analysis in this fifth edition. The Electronics Workbench examples of the fourth edition have been modified to work with Multisim and all instructions have been modified accordingly. This coverage is optional and is not a prerequisite for other topics within the text. Multisim continues to be one of the most widely employed Windows-based circuit analysis programs, particularly in educational institutions. Its success is based largely on the fact that it is very user-friendly and is quickly learned by computer-literate students. The text contains several dozen Multisim examples, loca
