Irwin adopts a learn-by-doing approach with the aim of developing a thorough understanding of the fundamentals of circuit analysis and their application to real-world problems. The text presents material in as clear and detailed a manner as possible, combining thorough explanations and worked examples, drill problems and answers. This edition has been streamlined to make room for the many new real-world examples and problems. It places greater emphasis on circuit analysis in the context of the real world of electrical engineering; includes numerous applications oriented examples; incorporates sections on circuit design to broaden readers understanding; integrates PSpice throughout, offering an accompanying disk that contains all PSpice material from the text with additional examples and an introduction to Schematic Capture; adds new coverage of many topics; demonstrates the connection between the Bode plot and the S-plane; adds figures that display the range of voltage, current, etc; and integrates new illustrations of various electrical components.
