This 3rd edition emphasizes applications by introducing three new chapters which guide readers meticulously through the design of feedback latches, the design of latches by composition, and an instructive, higher-order asynchronous circuit problem. This book serves as a wakeup call in the stagnant and dormant field of switching algebra and logic circuit design. It presents the material in a concise but thorough way. The topics presented are an in-depth presentation of switching algebra, a theory of elementary memory circuits (emphasizing fail-safe designs), compositional design of (combinational and memory) circuits, a new tree-approach to specifying and evaluating asynchronous sequential circuits, and finally an excursion into the field of industrial automation by presenting a unique programming technique (or language) for programmable logic controllers (PLCs). Be ready for the unorthodox and controversial.

Shimon Peter Vingron was born in Vienna, Austria, in 1936 and fled to England before the War with his family returning to Vienna in 1947. He studied mechanical engineering, physics and automation obtaining the degrees Ing., Dipl.-Ing., Dr. techn. and worked in industry in Germany and Austria. He lectured at the Ruhr University Bochum (Germany) and the Technische Universität Vienna,(Austria) and taught at the Engineering College Mödling, Austria. While at the Austrian Academy of Sciences he did research on sequential circuit theory. He has 2 patents, is the co-author of 2 books, and the author of 3.
