The book presents the basic concepts used in the design and analysis of digital systems and introduces the principles of digital computer organization and design. It provides various methods and techniques suitable for a variety of digital system design applications and covers all aspects of digital systems from the electronic gate circuits to the complex structure of a microcomputer system. It also includes applications of the read only memory (rom) and programmable logic array (pla).the flexible organization of the book permits it to be used in a variety of ways to suit the needs of courses in digital systems taught in electrical, electronics, computer science and engineering departments.featuresit covers all aspects of digital systems from the electronic gate circuits to the complex structure of microprocessor systemspresents the classical techniques for the logic design of combination and sequential circuitsit also facilitates a thorough understanding of the register-transfermethod used for the analysis and design of processor units and control unitstable of contantsbinary systems.boolean algebra and logic gates.simplification of boolean functions.combinational logic.combinational logic with msi and lsi.sequential logic.registers, counters, and the memory unit.register transfer logic.processor logic design.control logic design.computer design.microcomputer system design.digital integrated circuits.
