The author of this Web site presents a series of modules on various topics related to Digital Logic Systems. Even though he calls them "articles," the materials are quite extensive and thoroughly explains many key concepts. The first section is meant for people with little to no knowledge of digital system design. It covers the basics of logic gates and gives an example circuit that has practical value. A section on Boolean algebra has substantial information on fundamental algebraic operations, as well as introductions to truth tables and Karnaugh maps. The exclusive-OR operator and logic gate is given its own page, paying special attention to its unique behavior and accompanying theorems. Several other pages on related topics are also presented.
