Designed as a textbook for undergraduate students in Electrical Engineering, Electronics, Computer Science, and Information Technology, this up-to-date, well-organized study gives an exhaustive treatment of the basic principles of Digital Electronics and Logic Design. It aims at bridging the gap between these two subjects. The many years of teaching undergraduate and postgraduate students of engineering that Professor Somanathan Nair has done is reflected in the in-depth analysis and student-friendly approach of this book. Concepts are illustrated with the help of a large number of diagrams so that students can comprehend the subject with ease. Worked-out examples within the text illustrate the concepts discussed, and questions at the end of each chapter drill the students in self-study.
This book is an outgrowth of a set of notes prepared by the author for the first and second year of undergraduate students of various disciplines of engineering and applied sciences, such as electro-nics, computer science, and information technology. The text aims at giving clear and simplified explanations on the physical construction, relevant characteristics, principles of operation, and applications of several currently and widely used devices in electronic industries and research fields. As far as possible, mathematics is completely avoided. However, simple mathematical analyses are made in situations as and when they are required.
Designed as a text for undergraduate students of engineering in Electrical, Electronics, and Computer Science and IT disciplines as well as undergraduate students (B.Sc.) of physics and electronics as also for postgraduate students of physics and electronics, this compact and accessible text endeavours to simplify the theory of solid state devices so that even an average student will be able to understand the concepts with ease. The authors, Prof. Somanathan Nair and Prof. S.R. Deepa, with their rich and long experience in teaching the subject, provide a detailed discussion of such topics as crystal structures of semiconductor materials, Miller indices, energy band theory of solids, energy level diagrams and mass action law. Besides, they give a masterly analysis of topics such as direct and indirect gap materials, Fermi–Dirac statistics, electrons in semiconductors, Hall effect, PN junction diodes, Zener and avalanche breakdowns, Schottky barrier diodes, bipolar junction transistors, MOS field-effect transistors, Early effect, Shockley diodes, SCRs, TRIAC, and IGBTs. In the Second Edition, two new chapters on opto-electronic devices and electro-optic devices have been added. The text has been thoroughly revised and updated. A number of solved problems and objective type questions have been included to help students develop grasp of the contents. This fully illustrated and well-organized text should prove invaluable to students pursuing various courses in engineering and physics. DISTINGUISHING FEATURES • Discusses the concepts in an easy-to-understand style. • Furnishes over 300 clear-cut diagrams to illustrate the discussed. • Gives a very large number of questions—short answer, fill in the blanks, tick the correct answer and review questions—to sharpen the minds of the reader. • Provides more than 200 fully solved numerical problems. • Gives answers to a large number of exercises.
Designed as a textbook for the students of electronics and communi-cation engineering, and electrical and electronics engineering, it covers the subject of electromagnetism with a clear exposition of the theory in association with the practical applications. The text explains the physical and mathematical aspects of the highly complicated electromagnetic theory in a very simple manner. The book begins with a introductory chapter on vector theory and then moves on to explain the effectiveness of Ampere’s circuital law and Biot-Savart’s law in dealing with magnetostatic problems, derivation of Maxwell’s field equations from the fundamental laws of Faraday and Ampere, free-space solutions of wave equations, and the theory of skin effect. Finally, it concludes with the applications of Smith chart in solving transmission line problems and the theory of rectangular and circular waveguides. Key Features Large number of solved examples and chapter-end problems Appendices to give the solutions of wave equations in waveguides Three-dimensional figures to illustrate theories Generalized solution of Maxwell’s equations Besides undergraduate students of engineering, it would be useful for the postgraduate students of physics.
The present book is meant for the first-year engineering curricula of various universities in India. It describes the basic theories of electron dynamics, semiconductor physics, semiconductor diodes, bipolar junction transistors, field-effect (junction, MOS and CMOS) transistors, voltage and power amplifiers, oscillators, power electronic devices (SCR and UJT), and operational amplifiers. It further describes radio, mobile, fiber-optic, satellite and microwave communication systems. It also deals with the basic theories of radar, electronic instrumentation, Boolean algebra and logic functions. The book has more than 250 diagrams to illustrate the theories described and numerous worked examples.
This textbook for a one-semester course in Digital Signal Processing and Filter Design is suitable for undergraduate students of Electrical and Electronics Engineering, Electronics and Instrumentation Engineering, Instrumentation and Control Engineering, Electronics and Communication Engineering, Computer Science and Engineering, and Information Technology. Besides, it will also be a useful text for students pursuing applied sciences degree courses in Electronics, Computer Science, Computer Applications, and Information Technology. Though DSP is often treated as a complicated theoretical subject, this book through several worked examples strives to provide a motivating introduction to fundamental concepts, principles and applications of DSP. Building on the basic theory of DSP, the transformations techniques of signals such as Discrete-Time Fourier Transform (DTFT), Discrete Fourier Transform (DFT), Fast-Fourier Transform (FFT), and z-transform are discussed in detail. Several chapters are devoted to design and practical implementation schemes of analog and digital filters. The design of IIR filters using the Butterworth, Chebyshev, and Inverse Chebyshev approximations is illustrated. The design of FIR filters based on the Fourier-series and frequency-sampling methods, is discussed. Owing to their importance in DSP, the differential and difference equations are discussed in the penultimate chapter. The final chapter describes some of the practical applications of DSP.
