Electronic Devices and Circuits: Home

Objective: The objective of this course is to teach the principle, operation and characteristics of various electronic devices and their applications in electronic circuits.


Electronics is the science of how to control electric energy, energy in which the electronics have a fundamental role. Electronics deals with electrical circuits that involve active electrical components  such as vacuum tubes, transistors diodes and integrated circuits and associated passive electrical components and interconnection technologies. Electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuits.

The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible, and electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible.
