Electronics and Communication

Electronic engineering (also called electronics and communication engineering) is an electrical engineering discipline that uses active non-linear electrical components (such as semiconductor devices, especially transistors and diodes) to design electronic circuits, devices, integrated circuits, and their systems. The discipline also tends to design passive electronic components, usually based on printed circuit boards.

Electronics is a sub-field of a broader academic discipline of electrical engineering, but it means a wide range of engineering fields covering analog electronics, digital electronics, consumer electronics, embedded systems, and power electronics. Electronic engineering involves the implementation of applications, principles, and algorithms developed in many related fields, such as solid-state physics, radio engineering, telecommunications, control systems, signal processing, system engineering, computer engineering, engineering, instrumentation, power control, robotics and many more.
