Electronics, Second Edition briefly reviews basic electrical concepts before continuing the development of the subject with many self-assessment questions and worked examples. Each chapter begins with clear aims and objectives. Introducing necessary mathematics when needed, the book avoids advanced mathematical analysis, which can be left to computers and the many versions of circuit simulation software available. The emphasis of the text is on developing a clear understanding of the principles behind the design of circuits. It is suitable for an introductory university course on electrical circuits and analog and digital electronics.
