This introductory book explains, with completeness and clarity, how components and circuits are used in practical digital devices. It also describes any digital components or circuits that exist in integrated-circuit form. Chapter topics cover digital number systems, basic logic gates, Boolean algebra, combination and integrated circuits, basic storage elements: latches and flip-flops, counters, registers, arithmetic circuits, conversion devices and circuits, memory devices, and functional digital circuits. For individuals new to the electronics field, and for military personnel as a self-study reference.
