About the book:

Whatever profession you are preparing for, it will require a lot of hard work, and electronics is no exception.

This book is a complete manual on electronic devices and circuits and their applications. The well-represented sections on troubleshooting and practical applications make an important connection between theory and practice.

The topics covered are divided into two main categories. Chapters 1… 11 are dedicated to discrete devices and circuits, and chapters 12… 18 refer mainly to linear integrated circuits. To make the most of this book, you need to read, judge, solve problems, and work in the lab for a long time. You should not expect all the notions and working methods to seem clear to you from the beginning. Follow in detail the solution of each example and then perform the complementary exercise. Answer all the summary questions and check yourself by consulting the answers at the end of each chapter. If you have not understood a certain example or you cannot answer one of the questions, repeat that section until you have accumulated all the necessary knowledge and only then move on to the next section.

The self-assessment tests with multiple choice answers at the end of each chapter are a satisfactory way to check if you have understood and retained all the issues in that chapter.
