This book introduces the principles of modern digital electronics from basic Boolean algebra and K-maps to advanced FPGA- and ASIC-based system design. It provides a detailed coverage of the popular hardware description language (VHDL) supported with a large number of examples and case studies. This practical approach competently prepares readers to design combinational logic circuits and systems and create their own applications. Key features: (1) Comprehensive introduction to number systems, (2) Comprehensive introduction to Boolean algebra and K-maps, (3) Design and Minimization of combinational circuits, (4) Introduction to VHDL with all levels of abstraction, (5) Emphasis on gate-level and Register-Transfer Level designs, (6) Introduction to Quartus II CAD Software, (7) Extensive use of fully-worked examples throughout the text, and (8) Includes practical examples for the reader/student to carry out.
