About This Course
Electronics deals with electronics circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. The non-linear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and electronics is widely used information processing, telecommunications, and signal processing. Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered to be a branch of solid state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering.
