The field of electronics that is concerned with the engineering devices which make use of or produce digital signals is known as digital electronics. The electrical circuits used in such devices are large assemblies of logic gates which are packed into integrated circuits. The logic families can be broadly categorized into resistor-transistor logic, diode-transistor logic, transistor-transistor logic, emitter coupled logic and CMOS logic. Signals produced using digital systems can be transmitted without any significant degradation. They also provide easier information storage and access methods. Some of the important aspects of designing a digital circuit are representations, synchronous systems, asynchronous systems, computer architecture, design tools and register transfer systems. This book presents the complex subject of digital electronics in the most comprehensible and easy to understand language. Different approaches, evaluations and methodologies and advanced studies on digital electronics have been included herein. Those in search of information to further their knowledge will be greatly assisted by this book.
