Electronics & Communication engineering referred to as EC is an engineering discipline which uses the scientific knowledge of the behaviour and effects of electrons to develop components, devices, systems, or equipments (as in electron tubes, transistors, integrated circuits (IC) and Printed Circuit Boards (PCB`s)) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many subfields including those that deal with power, instrumentation engineering, telecommunications, semiconductor circuit design and many other.
