Solving circuit problems is less a matter of knowing *what* steps to follow than *why* those steps are necessary. And knowing the *why* stems from an in-depth understanding of the underlying concepts and theoretical basis of electric circuits. Setting the benchmark for a modern approach to this fundamental topic, Nassir Sabah’s **Electric Circuits and Signals** supplies a comprehensive, intuitive, conceptual, and hands-on introduction with an emphasis on creative problem solving.

**A Professional Education**

Ideal for electrical engineering majors as a first step, this phenomenal textbook also builds a core knowledge in the basic theory, concepts, and techniques of circuit analysis, behavior, and operation for students following tracks in such areas as computer engineering, communications engineering, electronics, mechatronics, electric power, and control systems. The author uses hundreds of case studies, examples, exercises, and homework problems to build a strong understanding of how to apply theory to problems in a variety of both familiar and unfamiliar contexts. Your students will be able to approach any problem with total confidence. Coverage ranges from the basics of dc and ac circuits to transients, energy storage elements, natural responses and convolution, two-port circuits, Laplace and Fourier transforms, signal processing, and operational amplifiers.

**Modern Tools for Tomorrow’s Innovators**

Along with a conceptual approach to the material, this truly modern text uses PSpice simulations with schematic Capture^{®} as well as MATLAB^{®} commands to give students hands-on experience with the tools they will use after graduation.

**Classroom Extras**

When you adopt **Electric Circuits and Signals**, you will receive a complete solutions manual along with its downloadable resources supplying additional material.
