Essence of Logic Circuits

Biographical Sketch Dr. Stephen H. Unger has made important contributions to logic circuit design theory over a period of many years. This has included significant work on hazards, flow table reduction, iterative circuits, clocking schemes, and self-timed systems. His book Asynchronous Sequential Switching Circuits is a basic reference in that field. Dr. Unger's graduate work was at MIT, and he subsequently was a member of the technical staff of Bell Telephone Laboratories for almost 5 years. His industrial experience also includes work at RCA Laboratories and IBM. He is a professor of both Computer Science and Electrical Engineering at Columbia University, where he recently was instrumental in organizing a degree program in computer engineering. He is a Fellow of the IEEE and of the AAAS. Mostly through the IEEE (as a member of the Board of Directors and former president of the IEEE Society on Social Implications of Technology), Dr. Unger has also been active in the areas of engineering ethics and technology policy.
