Combining analogue electronic circuits, basic digital electronic theory and circuitry and microprocessors in one volume, this new edition covers digital electronics while preparing the reader for more specialized options in electronics. The work introduces 8- and 16-bit microprocessors, presents their engineering applications and discusses the analysis and design of discrete component analogue circuits and the operation and application of digital integrated circuits. The operation and application of BJT, FET and MOSFET are covered and properties and applications of operational amplifiers are presented. Also included are digital electronics, Karnaugh maps and combinational and sequential logic, as well as circuit diagrams and worked examples.
