electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
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.
The massive ENIAC, which weighed 30 tons and filled an entire room, used some 18,000 vacuum tubes, 70,000 resistors, and 10,000 capacitors.
In December, 1945, it solved its first problem regarding the calculations for the hydrogen bomb. After its official unveiling in 1946, it was used to prepare artillery-shell trajectory tables and perform other military and scientific calculations.
2. A musical instrument that uses electronic circuits to produce music similar to that of a pipe organ.
3. An electrophonic instrument played by means of a keyboard in which sounds are produced and amplified by any of various electronic or electrical methods.
4. The electronic counterpart of the pipe organ where all tones and tone variations; such as, vibrato, tremolo, etc., are produced by electronic circuits instead of by pipes.
Electronic pacemakers can receive power from implanted batteries, radio frequency signals, biological energy sources, etc.
2. The technology of packaging electronic equipment.
In current usage, it refers to inserting discrete components, integrated circuits, and MSI and LSI chips (usually attached to a lead frame by beam leads) into plates through holes on multilayer circuit boards (also called cards), where they are soldered in place.3. The technology relating to the establishment of electrical interconnections and appropriate housing for electrical circuitry.
Electronic packages provide four major functions:
- Interconnection of electrical signals.
- Mechanical protection of circuits.
- Distribution of electrical energy (that is, power) for circuit function.
- Dissipation of heat generated by circuit function.
Examples of electronic parts are filters, capacitors, connectors, resistors, switches, relays, transformers, crystals, electron tubes, and semiconductor mechanisms.
2. A phasemeter or a device for measuring the difference in phase of two alternating currents of electromotive forces which makes use of electronic devices; such as, amplifiers and limiters, that convert the alternating-current voltages being measured into square waves whose spacings are proportional to phase.
The limiters mentioned in the above definitions refer to electronic circuits that are used to prevent the amplitudes of electronic waveforms from exceeding specified levels while preserving the shapes of the waveforms at amplitudes less than the specified levels.
Also known as amplitude limiters; amplitude-limiting circuits; automatic peak limiters; clippers; clipping circuits; limiter circuits; and peak limiters.
2. A piano without a sounding board, in which vibrations of each string affect the capacitance of a capacitor microphone and then produce audio-frequency signals that are amplified and reproduced by a loudspeaker.
2. Polarization arising from the displacement of electrons with respect to the nuclei with which they are associated, upon application of an external electric field.
2. A radio navigation system used in hydrographic surveying (surveying, and mapping of the oceans, seas, and rivers) which provides circular lines of positions.
3. An apparatus used to measure ship-to-shore distances by measuring the time elapsed for a radio echo to take place.
A computer power supply converts alternating current into multiple direct current voltages; for example, twelve volts is commonly used for drives, while 3.3 volts and 5 volts are used by the chips and other motherboard components.2. A device used to convert, regulate, and transmit external power for use by the components housed inside a computer chassis.
The EPC has digits to identify the manufacturer, product category and the individual item.
Such products may be used as tools and controls in communications, detection, amplification, computation, inspection, testing, measurement, operation, recording, analysis, and other functions employing electronic principles.
The diamond-point stylus of a permanent-magnet dynamic pickup is moved over the surface being checked out, and the resulting varying voltage is amplified, corrected, and measured with a meter calibrated to read directly in micro-inches of deviations or differences from the smoothness desired.
A maser is a device for the creation, amplification, and transmission of an intense, highly focused beam of high-frequency radio waves.
The name maser is an acronym for "microwave amplification by stimulated emission of radiation", microwaves being radio waves of short wavelength, or high frequency.
