This paper constitutes an introduction to the world of digital electronics and assumes little or no previous knowledge of the subject on the part of the reader. A pragmatic approach is taken in the presentation of the basic building blocks: inverters, gates, flip-flops, etc. Boolean algebra and the mathematics for mapping digital circuits are not treated here. Rather, this paper explores the terminology of digital circuits and the realization of circuit elements in popular digital IC technologies. A table of possible areas of application for digital circuits the automobile is included.
