Contemporary Electronics: Fundamentals, Devices, Circuits and Systems offers a modern approach to fundamental courses for the electronics and electrical fields. It is designed for the first two or three electronic courses in the typical associate degree program in electronic technology. It includes both DC and AC circuits as well as semiconductor fundamentals and basic linear circuits. It addresses the numerous changes that have taken place over the past years in electronics technology, industry, jobs, and the knowledge and skills required by technicians and other technical workers. It can be used in separate DC and AC courses but also in a combined DC/AC course that some schools have adopted in the past years. Contemporary Electronics offers the student the benefit of being able to use a single text in two or three courses minimizing expenses.
