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.
