The perfect introduction to digital concepts, applications, and design, Introduction to Digital Electronics uses a logical organization of topics, clear explanations, and current examples to present key information in a way that is easy to grasp. Unique in its approach, this book covers combinational and sequential logic circuits using CPLDs while still covering circuit design at the gate level using TTL/CMOS devices. The book begins by introducing combinational logic, including detailed explanations for implementing circuits in Altera Quartus II software and CPLDs. The material continues to be presented at the gate level, preparing readers to successfully navigate more complicated areas like functional circuits. Using formal problem-solving concepts, combinational design is then covered, which includes a large combinational design that includes the building and simulation of each component, marking a valuable departure from traditional books in the field which do not cover large-scale design at a combinational level. Additional coverage includes sequential circuits with an emphasis on relevant and useful circuits, and microprocessor and memory concepts.
