Preface
This is the book that I wish I had when I first
started exploring electronics nearly half a century
ago. In those days, transistors were only just
making their debut and integrated circuits were
completely unknown. Of course, since then much
has changed but, despite all of the changes, the
world of electronics remains a fascinating one.
And, unlike most other advanced technological
disciplines, electronics is still something that you
can ‘do’ at home with limited resources and with a
minimal outlay. A soldering iron, a multi-meter,
and a handful of components are all that you need
to get started. Except, of course, for some ideas to
get you started—and that’s exactly where this book
comes in!
The book has been designed to help you
understand how electronic circuits work. It will
provide you with the basic underpinning
knowledge necessary to appreciate the operation of
a wide range of electronic circuits including
amplifiers, logic circuits, power supplies and
oscillators.
The book is ideal for people who are studying
electronics for the first time at any level including a
wide range of school and college courses. It is
equally well suited to those who may be returning
to study or who may be studying independently as
well as those who may need a quick refresher. The
book has 19 chapters, each dealing with a particular
topic, and eight appendices containing useful
information. The approach is topic-based rather
than syllabus-based and each major topic looks at a
particular application of electronics. The relevant
theory is introduced on a progressive basis and
delivered in manageable chunks.
In order to give you an appreciation of the
solution of simple numerical problems related to
the operation of basic circuits, worked examples
have been liberally included within the text. In
addition, a number of problems can be found at the
end of each chapter and solutions are provided at
the end of the book. You can use these end-ofchapter
problems to check your understanding and
also to give you some experience of the ‘short
answer’ questions used in most in-course
assessments. For good measure, we have included
70 revision problems in Appendix 2. At the end of
the book you will find 21 sample coursework
assignments. These should give you plenty of ‘food
for thought’ as well as offering you some scope for
further experimentation. It is not envisaged that you
should complete all of these assignments and a
carefully chosen selection will normally suffice. If
you are following a formal course, your teacher or
lecturer will explain how these should be tackled
and how they can contribute to your course
assessment. While the book assumes no previous
knowledge of electronics you need to be able to
manipulate basic formulae and understand some
simple trigonometry in order to follow the
numerical examples. A study of mathematics to
GCSE level (or equivalent) will normally be
adequate to satisfy this requirement. However, for
those who may need a refresher or have had
previous problems with mathematics, Appendix 6
will provide you with the underpinning
mathematical knowledge required.
In the later chapters of the book, a number of
representative circuits (with component values)
have been included together with sufficient
information to allow you to adapt and modify the
circuits for your own use. These circuits can be
used to form the basis of your own practical
investigations or they can be combined together in
more complex circuits.
Finally, you can learn a great deal from building,
testing and modifying simple circuits. To do this
you will need access to a few basic tools and some
minimal test equipment. Your first purchase should
be a simple multi-range meter, either digital or
analogue. This instrument will allow you to
measure the voltages and currents present so that
you can compare them with the predicted values. If
you are attending a formal course of instruction and
have access to an electronics laboratory, do make
full use of it!

A note for teachers and lecturers
The book is ideal for students following formal
courses (e.g. GCSE, AS, A-level, BTEC, City and
Guilds, etc.) in schools, sixth-form colleges, and
further/higher education colleges. It is equally well
suited for use as a text that can support distance or
flexible learning and for those who may need a
‘refresher’ before studying electronics at a higher
level.
While the book assumes little previous
knowledge students need to be able to manipulate
basic formulae and understand some simple
trigonometry to follow the numerical examples. A
study of mathematics to GCSE level (or beyond)
will normally be adequate to satisfy this
requirement.
However, an appendix has been added
specifically to support students who may have
difficulty with mathematics. Students will require a
scientific calculator in order to tackle the end-ofchapter
problems as well as the revision problems
that appear at the end of the book.
We have also included 21 sample coursework
assignments. These are open-ended and can be
modified or extended to suit the requirements of the
particular awarding body. The assignments have
been divided into those that are broadly at Level 2
and those that are at Level 3. In order to give
reasonable coverage of the subject, students should
normally be expected to complete between four and
five of these assignments. Teachers can
differentiate students’ work by mixing assignments
from the two levels. In order to challenge students,
minimal information should be given to students at
the start of each assignment. The aim should be that
of giving students ‘food for thought’ and
encouraging them to develop their own solutions
and interpretation of the topic.
Where this text is to be used to support formal
teaching it is suggested that the chapters should be
followed broadly in the order that they appear with
the notable exception of Chapter 14. Topics from
this chapter should be introduced at an early stage
in order to support formal lab work. Assuming a
notional delivery time of 4.5 hours per week, the
material contained in this book (together with
supporting laboratory exercises and assignments)
will require approximately two academic terms (i.e.
24 weeks) to deliver in which the total of 90 hours
of study time should be divided equally into theory
(supported by problem solving) and practical
(laboratory and assignment work). The
recommended four or five assignments will require
about 25 to 30 hours of student work to complete.
Finally, when constructing a teaching programme it
is, of course, essential to check that you fully
comply with the requirements of the awarding body
concerning assessment and that the syllabus
coverage is adequate.
