As an elementary digital design text or refresher for practicing engineers, this book covers number systems, Boolean algebra, combinational design, circuit minimization, complex circuits, and sequential design. It addresses the mathematical and logical underpinnings of digital design while at the same time showing readers how to construct complex circuits from simpler building blocks. Each chapter is accompanied by a software module designed to dynamically illustrate the concepts in the text. Experimentation in the modules is encouraged, and in all cases, the software offers dynamic and immediate feedback so that any of the user?s mistakes can be easily and quickly detected. The final chapter is devoted to the application of these designs in novel creations such as robots and other intelligent machines. The book also covers the aesthetics of digital design as a method of creating efficient models. This text is a uniquely engaging and interactive complement to the lectures and problem sets of any digital design course.
