Electronic System

Electronic system, a group of electronic circuits and components which are designed to accomplish one or more complex functions. Examples include telecommunication systems, computer systems, power systems, radar systems, electronic music systems, and many others. Electronics is one of the  branch of science and technology that deals with electrical circuits involving active electrical components such as vacuum, transistors, diodes and integrated circuits. The nonlinear characteristics of these components and their ability to control electron flows makes amplification of weak signals possible, and is usually applied to information and signal processing. Electronics is a distinct from electrical and electro-mechanical science and technology, which deals with the generation, distribution, switching, storage and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays,transformers, resistors and other passive components. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers and vacuum tubes.

Electronic System And Components

An electronic device is any physical entity in an electronic system used to affect the electrons or their associated fields in a desired manner consistent with the intended function of the electronic system. Components are usually intended to be connected together, usually by being soldered to a printed circuit board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Components are packaged singly or in more complex groups as integrated circuits. Commonly used systems of electronic components are capacitors, inductors, resistors, diodes, transistors, etc. Components are often categorized as active (e.g. transistors and thyristors) or passive (e.g. resistors and capacitors).

Electronics Theory

A mathematical method is integral to the study of electronics. To become professional in electronics it is also necessary to become proficient in the mathematics of circuit analysis.
Circuit analyses are the study of methods of solving generally linear systems for unknown variables such as the voltage at a certain node or the current through a certain branch of a network.
