This book presents the basic concepts of electronic devices and circuits in an easy to understand manner. The main topics covered include semiconductor diodes and their application in rectifiers and voltage regulators; transistors, their configurations and application in amplifier and oscillator circuits; operational amplifiers and their applications; and number systems and the fundamentals of analogue communication circuits and basic transducers.

A number of design and analytic numerical problems have been included to help the student understand the application of the concepts. The book will be useful for the first year course in Engineering.
