Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
A wattmeter which uses two matched electronic voltmeters to give a reading proportional to the product of two voltages, on a scale calibrated to read power values directly.
One voltage is that which appears across the load, and the other is obtained across a resistor in the series with the line.
electronic waveform synthesizer
An apparatus that uses electron devices to generate an electrical signal of a desired waveform.
electronic work function
1. The energy which is necessary to remove an electron with the Fermi energy in a solid to the energy level of an electron at rest in a vacuum outside the solid.
2. The energy required to raise an electron with the Fermi energy (average energy of electrons in a metal) in a solid to the energy level of an inactive electron in a vacuum outside the solid.
The term Fermi energy is named after Enrico Fermi (1901-1954), an Italian nuclear physicist and refers to the level in the distribution of electron energies in a solid at which a quantum state is equally likely to be occupied or empty.
The use of electronic circuits and electron tools to reproduce symbols; such as, an alphabet, in a specified order on an electronic display machine for the purpose of transferring information from a source to a viewer of the display instrument.
By electronic means or in an electronic manner; for example, stored in or controlled by a computer.
electronically agile radar
1. An airborne radar in which the beam from phased array antennae changes form and direction according to electronic velocities or speeds.
2. An airborne radar that uses a phased-array antenna which changes radar-beam forms and beam positions at electronic speeds.
When combined with digital processing of the radar returns, it can simultaneously provide such functions as beacon-locating, forward-looking mapping, navigation updating, terrain avoidance, and terrain-following in manned strategic bombers and other aircraft.
electronically programmable logic device, ELPD
A field programmable logic device with transistor rather than fuse links for controlling the signal paths in its fixed array of logic blocks and connections.
electronically tuned oscillator
An oscillator in which the operating frequency is modified by changing an electrode voltage or current.
To install electronic systems.
1. The study and application of the conduction of electric charges in various media, including vacuums, gaseous media, and semiconductors.
2. The science of all systems involving the use of electrical instruments used for communication information processing, and control.
3. That field of science and engineering which deals with electron systems, circuits, and devices that control the flow of electrons.
4.The name given to that branch of electrical engineering that deals with tools the operations of which depend on the movement of electrons in space as opposed to the movement of electrons in liquids or solid conductors; for example, radio tubes, photoelectric cells, etc.
The term electronics refers to a large number of different phenomena and devices in which useful electrical effects are achieved through control of the motion of electrons.
The fact that the time in which we live is sometimes referred to as "the electronic age" indicates what widespread consequences are involved.
A representative partial list of electronic devices today includes such diverse applications as rectifiers, amplifiers, integrated circuits, memories, microwave sources and receivers, light-emitting devices, light-detecting devices, and solar cells to convert solar energy into electricity.
An engineer whose training includes a degree in electronic engineering from an accredited college or university, a degree in electrical engineering with a major in electronics, or comparable knowledge and experience as required for working with electronic circuits and tools.
electronics industry (s) (noun)
, electronics industries (pl)
The industrial organizations engaged in the design, development, manufacture, and the substantial assembly of electronic equipment, systems, assemblies, and components.
A serviceman who is qualified to repair and to maintain electronic equipment.
A pulse generator used to apply voltages to the body for activating muscles, identifying nerves, and for other medical diagnoses for identifying or determining the natures and causes of diseases or injuries.
A technician with both theoretical and practical training in electronics technology who is qualified to work under the direction of an electronics engineer or independently in assembling, testing, and repairing electronic equipment, in factories, laboratories, and in private business.
