Now revised with a stronger emphasis on applications and more problems, this new Fourth Edition gives readers the opportunity to analyze, design, and evaluate linear circuits right from the start. The book's abundance of design examples, problems, and applications, promote creative skills and show how to choose the best design from several competing solutions. * Emphasis on circuit design. Integrated treatment of analysis and design enhances students understanding of circuit fundamentals. The text gets students involved in design early, so they can recognize how their newly acquired knowledge can be applied to practical situations. * Early introduction to the Op-Amp. The authors introduce students to the ideal Op-Amp early and often, allowing you to teach practical designs that students can actually build and use.
