Now in its third edition, this text provides coherent and comprehensive coverage of digital circuits. This new edition incorporates VHDL programmes at the end of each chapter. It is designed for undergraduate students studying engineering disciplines such as electronics, electronics and communication, electronics and instrumentation, telecommunications, medical electronics, computer science and engineering, electronics, and computers and information technology. Written in a student-friendly style, the book provides an excellent introduction to digital concepts and basic design techniques of digital circuits. It discusses Boolean algebra concepts and their application to digital circuitry, and examines both combinational and sequential circuits. It provides numerous fully worked-out, laboratory tested examples to give students a solid grounding in the related design concepts, and includes a number of short questions with answers, review questions, fill in the blanks with answers, multiple choice questions with answers and exercise problems at the end of each chapter.
