Debashis De - Basic Electronics

Basic Electronics has been written to serve as a textbook for core science and technology courses in engineering colleges and universities. This book is not only useful for students of science and technology, but also for readers from other fields aspiring to enhance their knowledge of electronics through self-study. The objective of the book is to develop the basic ability to understand electronics as a science that forms the core of engineering and technology in general. The basic prerequisite for those using this book is the alert mind. The required physics and mathematics has been developed throughout the book, and no prior knowledge of physical electronics has been assumed.

builds the foundation of electronics with a detailed analysis of crystalline materials, classification of materials, intrinsic and extrinsic semiconductors, electrical conduction phenomenon, continuity equation and the Hall Effect. The book then proceeds to focus on the major categories of electronic devicesthe diode, bipolar junction transistor and field-effect transistorwith two chapters devoted to each device.

discusses the conceptual development of feedback in amplifiers through block diagrams, properties of positive and negative feedback, calculations of open-loop gain, closed-loop gain, feedback factors, topologies of feedback amplifier, the effect of feedback on gain, input impedance and output impedance, practical implementation of the feedback topologies, sensitivity, bandwidth stability and the effect of positive feedback.

is devoted to a detailed examination of the working principle of an oscillator, the various classifications of oscillators along with a detailed examination of Barkhausen criteria.

, deals with the key instruments of electronic measurement with special emphasis on the most versatile instrument of electronic measurement, the cathode-ray oscilloscope.

Simplicity is the key word when it is a question of building a foundation. The hallmark of this book is the presentation of the most complex theories in a manner that facilitates a lucid understanding of the fundamentals while establishing the platform for the next phase of subject development. Through simple language and clear-cut presentation, the book presents electronics intelligently.

There are numerous books on this subject, with a varying degree of depth and coverage that map the courses on electronics as offered by different institutions. This book emphasizes the importance of observing the applications by concentrating on the fundamentals. This approach will sustain an efficient assimilation of concepts in a coherent way. The primary aim of writing Basic Electronics is to establish a strong foundation in electronics and provide tools for self-assessment and further learning.

To complement the attempt at providing a student-friendly text, a comprehensive learning package has been combined with this book. Each chapter ends with: Important Formulae, Points to Remember, Objective Questions, Review Questions, Practice Problems and Suggested Readings. The companion Web site features a comprehensive lesson plan for instructors, which allows them to design and modify courses. An evaluation module for the students allows them to assess their progress. And a unique set of animated representations of key circuits and their functions, which makes the learning process simpler.

REVIEWERS

The final form in which Basic Electronics has been presented here would not have been possible without the feedback received from our reviewers. While we could not incorporate every suggestion from our reviewers, we do acknowledge that their feedback was invaluable in our attempt at creating the best possible basic electronics textbook.
