Electronic engineering
Electronics engineering, or electronic engineering, is an engineering discipline which utilizes non-linear and active electrical components (such as electron tubes, and semiconductor devices, especially transistors, diodes and integrated circuits) to design electronic circuits, devices and systems. The discipline typically also designs passive electrical components, usually based on printed circuit boards.The term ""electronic engineering"" denotes a broad engineering field that covers subfields such as analog electronics, digital electronics, consumer electronics, embedded systems and power electronics. Electronics engineering deals with implementation of applications, principles and algorithms developed within many related fields, for example solid-state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, electric power control, robotics, and many others.The Institute of Electrical and Electronics Engineers (IEEE) is one of the most important and influential organizations for electronics engineers.
