The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the field of electronics engineering, and includes the hardware design side of computer engineering.

The study of new semiconductor devices and their technology is sometimes considered as a branch of physics. This page focuses on engineering aspects of electronics.

Overview of electronic systems and circuits


Electronic systems are used to perform a wide variety of tasks. The main uses of electronic circuits are the controlling, processing and dof information, and the conversion and distribution of electric power. Both of these uses involve the creation or detection of electromagnetic fields and electric currents. While electrical energy had been used for some time to transmit data over telegraphs and telephones, the development of electronics truly began in earnest with the advent of radio. One way of looking at an electronic system is to divide it into the following parts:
