About Of The Book :
"Basic Electronics" by Ravish Aradhya H V.
"Basic Electronics" is a textbook that covers the fundamental concepts of electronics in a comprehensive manner. The book is primarily designed for undergraduate students pursuing electronics, electrical, and communication engineering courses. The book is structured in such a way that it is easy to understand for beginners, with step-by-step explanations and illustrations to guide the reader.
Some of the topics covered in the book include electronic components, electronic circuits, amplifiers, oscillators, and digital electronics. The book also includes solved examples and practice problems to help readers understand the concepts better.
Overall, "Basic Electronics" by Ravish Aradhya H V is a well-regarded textbook in the field of electronics and is considered a useful resource for students pursuing electronics and electrical engineering courses.
Basic Electronics is a common course for all engineering disciplines. Students of all engineering
disciplines, particularly non-electrical engineering disciplines, find it very difficult to understand the
basic concepts of this subject. Most of the currently available textbooks provide high-end information,
but fail to provide elaborate and detailed explanation on most topics. Also, there is no single book that
covers the entire syllabus of any university and provides all the necessary information.
Even for the students of electrical engineering disciplines, there is a need for catering to strong
fundamentals, so that they can be more comfortable at higher semester levels. Most current titles have not
given enough scope for the basics. Hence, a thorough attempt has been made to cover the entire syllabus
in one book, with a lot of emphasis on basics. This text covers the Basic Electronics syllabi of more than
12 different leading universities of India. Much effort has been made to present the information in a lucid
and easily understandable way, so that it is effective for the students at the first/second semester levels.
Also, the content is designed to help all classes of students at lower and even in higher semester levels.

Chapter Organisation
The book is organised into 10 well-designed chapters, covering almost all the needs of a first course in
electronics. The overview of each chapter is outlined below:
Chapter 1 covers the fundamentals of semiconductor physics, charge carriers in semiconductors
and doping concepts. The PN-junction formation, its behaviour under different biasing conditions,
characteristics and equivalent circuits are discussed.
Chapter 2 deals with the fundamentals of a semiconductor PN-junction diode, its characteristics and
load-line analysis. All important applications of junction diodes such as rectifiers, voltage multipliers,
wave-shaping circuits and basic logic gates are covered with maximum care. The other sub-systems of
power supply, such as filters and regulators, are also designed and analysed.
Chapter 3 presents another very important semiconductor three-terminal device, the Bipolar Junction
Transistor (BJT). The fundamentals of device construction, characteristics, and configurations of
operation are covered. Different biasing methods and applications of BJT are covered to a large extent.
Chapter 4 introduces applications of BJT such as amplifiers, oscillators and feedback concepts. Amplifier
classification, design analysis, feedback concepts, effect of feedback on the performance of BJT circuits
is discussed. Oscillator classification and design analysis are also presented in this chapter.
Chapter 5 explains fundamentals of communication, modulation/demodulation methods and their
performance comparison. The chapter also discusses radio and television communication applications.
Chapter 6 covers fundamentals of important linear integrated circuits such as operational amplifier, timer
and Phase-Locked Loops (PLLs). The internal architecture, characteristics and useful applications of
these devices are discussed. The worked examples, multiple-choice questions and chapter-end summary
aims to make the reader more confident in using these ICs in real-life applications.
Chapter 7 presents the fundamentals of switching theory and logic design, covering basics to real-world
applications, both in combinational and sequential systems. Applications such as arithmetic circuits,
latches, flip-flops, registers, counters, etc. are also discussed.
Chapter 8 deals with fundamentals of measuring and display instruments. Measuring instruments like
voltmeters, ammeters, multimeters and display instruments like cathode ray oscilloscopes are discussed
in this chapter. Measurements such as frequency and phase angle for signals are covered thoroughly.
Chapter 9 explains fundamentals of transducers. In real-world applications, transducers play a vital
role and the chapter provides a very good introduction for readers.
Chapter 10 covers fundamentals of other very important semiconductor devices such as Field Effect
Transistors (FETs), Metal Oxide Semiconductor FETs (MOSFETs), Unijunction Transistors (UJTs), etc.
The fundamentals of device construction, characteristics, and configurations of operation are dealt with.
Different biasing methods and applications of FETs are discussed to a large extent. Silicon Controlled
Rectifier (SCR), another very important semiconductor device that finds strong applications in power
electronics, is also presented in this chapter.
Considerable efforts have been put in to the layout of different chapters, preparation of the material
and of presentation pedagogy. A large variety of exercise problems provided at the end of each chapter
will certainly help the reader develop strong fundamental knowledge. I expect and hope that all readers
would highly benefit from these pedagogical features during self-study. Budding engineers will find the text very useful in updating their knowledge base.
