Digital Circuit Projects: An Overview of Digital Circuits Through Implementing Integrated Circuits - Second Edition

Digital circuits, often called Integrated Circuits or ICs, are the central building blocks of a Central Processing Unit (CPU). To understand how a computer works, it is essential to understand the digital circuits which make up the CPU. This text introduces the most important of these digital circuits; adders, decoders, multiplexers, D flip-flops, and simple state machines. What makes this textbook unique is that it puts the ability to understand these circuits into the hands of anyone, from hobbyists to students studying Computer Science. This text is designed to teach digital circuits using simple projects the reader can implement. But unlike most lab manuals used in classes in Digital Circuits or Computer Organization classes, this textbook is designed to remove the barrier of a laboratory infrastructure needed in a face-to-face environment at a college or university. This textbook is designed to be used by the reader to create the circuits in their own homes. The textbook is free. The cost of the kits needed to do the labs is reasonable. And the projects are well documented and can be implemented by even novices to electronic projects. This text allows professors to add laboratory projects in digital circuits to students in online classes in Computer Organization. This enhances these classes with interesting and fun exercises that reinforce the classroom topics. This text can also be used by a hobbyist who wants to learn more about digital circuits and how computers work. The material is presented at a level that someone with no experience in digital circuits and electronics can successfully complete the projects, and gain an understanding of the circuits which go into making up a computer. The second edition of this includes a chapter on Boolean Algebra for professors who would like to include a more formal background into digital circuits. It also changed the chapter designed to give a context for the CPU to reference a relatively simple CPU developed by the author in Logisim. For someone who is interested in digital circuits, this book is worth downloading. Note: Often it is easier to use a MS Word file rather than a pdf file. If you would like the book as a Word document and not a pdf, please contact the author at ckann(at)gettysburg.edu, and he will mail it to you. The main reason for this is to get some sort of feedback on who is using the text.
