Digital systems are created to perform data processing and control tasks. What distinguishes one system from another is an architecture tailored to efficiently execute the tasks for which it was designed. A desktop computer and an automobile’s engine controller have markedly different attributes dictated by their unique requirements. Despite these differences, they share many fundamental building blocks and concepts. Fundamental to digital system design is the ability to choose from and apply a wide range of technologies and methods to develop a suitable system architecture. Digital electronics is a field of great breadth, with interdependent topics that can prove challenging for individuals who lack previous hands-on experience in the field.
