Basic Electronics

This book is intended to serve as a textbook for the students taking the course on Basic Electronics (First Semester B.E.) prescribed by the VTU. Fundamental principles and applications of electronics are described herein in a clear and concise way with explanatory diagrams. The language is lucid and simple. Physical aspects are explained with ample details; mathematical derivations are also given, where necessary. Numerical problems which are typically set in examinations are included in the book to illustrate the application of the principles contained in the text. Many of these problems are worked out, and the rest are left as exercises for the students. The answers to such problems are given for the benefit of the students. The objective-type and the review questions included in the book reflect the type of questions set in different examinations. The book contains 13 chapters. Chapter 1 deals with semiconductor diodes. Diode applications are treated in Chapter 2. Chapters 3 and 4 are devoted to junction transistor characteristics, transistor biasing and amplification. Chapter 5 is concerned with field-effect transistors. Special devices like silicon-controlled rectifiers and unijunction transistors form the subject-matter of Chapter 6. Basic amplifiers feedback in amplifiers and oscillators are discussed in Chapters 7, 8, and 9, respectively. Operational amplifiers are taken up in Chapter 10. Modulation and communication systems are included in Chapter 11, Number systems and digital logic are covered in Chapter 12. The cathode ray oscilloscope is incorporated in Chapter 13.
