Detailed Description
Sarma: Introduction to Electrical Engineering


1. The readability of the text and the level of presentation, from the student's viewpoint, are given utmost priority. The quantity of subject matter, range of difficulty, coverage of topics, numerous illustrations, a large number of comprehensive worked-out examples, and a variety of end-of-chapter problems are given due consideration, to be sure that engineering is not a "plug-in" or "cook-book" profession, but one in which reasoning and creativity are of the highest importance.

2. The theory has been developed from simple beginnings in such a manner that it can readily be extended to new and more complicated situations. The art of reducing a practical device to an appropriate mathematical model and recognizing its limitations has been adequately presented.

3. The student will be motivated to go through the sequence of understanding physical principles, processes, modeling, using analytical techniques, and finally, designing.

4. Engineers habitually break systems up into their component blocks for ease of understanding. The building-block approach has been emphasized, particularly in Part II concerning analog and digital systems.

5. Considering the world of electronics today, both analog and digital technologies are given appropriate coverage. Since students are naturally interested in such things as Op-Amps, integrated circuits, and microprocessors, modern topics that can be of great use in their career are emphasized in this text.

6. The electrical engineering profession focuses on information and energy, which are the two critical commodities of any modern society. In order to bring the message to the forefront for the students' attention, Parts III, IV, and V are dedicated to energy systems, information systems, and control systems, respectively. However, some of the material in Parts I and II is critical to the understanding of the latter. Information systems have been responsible for the spectacular achievements in communication in recent decades. Concepts of control systems, which are not limited to any particular branch of engineering, are very useful to every engineer involved in the understanding of dynamics of various types of systems.

7. While solid-state electronics, automatic control, IC technology, and digital systems have become common place in the modern EE profession, some of the older, more traditional topics, such as electric machinery, power, and instrumentation, continue to form an integral part of the curriculum, as well as of the profession in real life. Due attention is accorded in this text to such topics as three-phase circuits and energy systems.

8. Appendices provide useful information for quick reference on selected bibliography for supplementary reading, and a review of topics on the EIT Exam.

9. Basic material introduced in this book is totally independent of any software that may accompany the usage of this book, and/or the laboratory associated with the course. The common software in usage, as of writing this book, consists of Windows, Word Perfect, PSPICE, Math CAD, and MATLAB. There are also other popular specialized simulation programs such as Signal Processing Workstation (SPW) in the area of analog and digital communications, Very High Level Description Language (VHDL) in the area of digital systems, Electromagnetic Transients Program (EMTP) in the field of power, and SIMULINK in the field of control. In practice, however, any combination of software that satisfies the need for word-processing, graphics, editing, mathematical analysis, and analog, as well as digital, circuit analysis should be satisfactory.
