Basic electronics is a compulsory subject for the first year engineering students from all the
disciplines. This book is primarily intended to serve as a textbook in accordance with the syllabus
of Basic Electronics offered by various universities in India. It also meets the needs of those readers
who want to gain a sound understanding of the principles of electronics.
This book has been written in a very simple and lucid manner. Every effort has been made
to make the treatments simple and comprehensive. Throughout the book, the stress has been given
on fundamental concepts through illustrative examples. Neat and clear diagrams have been used
for explanation.
A large number of self explanatory accurate diagrams and tables have been used to
supplement the text. Exercises and problems are also provided. This will help the students to
prepare accordingly.
This book is also intended as a textbook for the use in Electronics and Communication
courses in polytechnics, IETE, AMIE and for various Engineering Electronics examinations. Thus,
primarily designated as an undergraduate textbook for students of science and technology, this
study will provide balanced coverage of devices, analog and digital circuits, with an emphasis on
analog electronics.
I have no claim to the original research in preparing this book. Liberal use of the materials
available in the work of eminent authors has been made. I have tried to fashion the vast amount of
material available from primary and secondary sources into coherent body of description and
analysis.
Errors might have crept in despite utmost care to avoid them and author shall be grateful if
these are reported along with other suggestions for improvement of the book.
