The fundamentals and implementation of digital Electronics are essential to understanding the design and working of consumer/industrial electronics, communications, embedded systems, computers, security and military equipment. Devices used in applications such as these are constantly decreasing in size and employing more complex technology. It is therefore essential for Engineers and students to understand the fundamentals, implementation and application principles of digital Electronics, devices and integrated circuits. This is so that they can use the most appropriate and effective technique to suit their technical need.
