Digital Logic

Electronic techniques have come to dominate mathematical computation and industrial control. Ample evidence for this is provided by the proliferation of pocket calculators, the boom in small computers for both domestic and business use and of course the development of very large computers capable of performing enormous calculations at faster and faster speeds. In industry purpose-built computers and robots monitor and perform a wide range of operations from menial tasks such as paint spraying, batch counting and sorting to very precise repetitive machine tool control. Electronic design in this field is based on digital logic circuits. In recent years the application of such circuits has spread to video games, wristwatches, audio and television, the telephone system, automobile instrumentation, sewing machines and washing machines, among many examples, to create a digital electronic revolution.
