Electronics

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

Electronic devices today

Electronic devices and systems today perform a wide variety of tasks.

The main uses of electronic circuits are the controlling, processing and distribution of 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.

CAD/ CAM of electronic circuits

Todays electronics engineers enjoy the ability to design circuits using premanufactured building blocks such as power supplies, resistors, capacitors, semiconductors such as transistors, and integrated circuits. Electronic design automation software programs include schematic capture programs such as ORCAD and gEDA used to make circuit diagrams and printed circuit board layouts.
