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.
2. A digital instrument display for speed, miles, fuel level, fuel consumption clock, etc.
These signals are processed to give the nature and deployment of enemy warning and missile guidance radars, fire control, and countermeasures systems.
3. Electronic systems, apparatus, and operations for obtaining information concerning a military enemy's capabilities, intentions, plans, and order of battle.
2. Any electrical or electromagnetic disturbance that causes undesirable responses in electronic equipment.
3. An electric or electromagnetic disturbance which causes undesirable responses in electronic equipment.
Electric interference refers specifically to an interference that is caused by the operation of an electric apparatus which is not designed to radiate electromagnetic energy.
2. Radiation or re-radiation of electromagnetic waves so as to impair the usefulness of a specific segment of the radio spectrum that is being used by a military enemy for communication or radar.
3. To interfere with or to prevent the clear reception of (broadcast signals) by electronic methods.
Keying is the forming of signals; such as, for telegraph transmission, by modulating a direct-current or other carrier between discrete values of some characteristic.
Keying is also defined as the shaping of a signal to convey information, known as modulation or the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal which can be physically transmitted with an alternating-current source; for example, by interrupting it or by suddenly changing its amplitude, frequency, or some other characteristic.
2. An electronically actuated substitute for the human larynx, designed for people who have lost the use of their vocal cords.
A pulse generator feeds the entire spectrum of voice frequencies into the throat through either a tube inserted into the mouth or with a small loudspeaker held against the throat.
The resulting sound waves in the throat are formed into words essentially by the normal movements of the jaws, the lips, and the tongue.
2. In facsimile copying, a method by which a spot on a cathode-ray tube moves across the copy by electronic actions.
3. A method that provides motion of the scanning spot along the scanning line controlled by electronic procedures.
4. Facsimile scanning in which a spot on a cathode-ray tube moves across the copy electronically while the record sheet or subject copy is moved mechanically in a perpendicular direction.
2. A device used to capture the sound waves of conversations originating in an supposedly private setting in a form, usually as a magnetic tape recording, which can be used against the target by anyone with negative intentions.
2. A portable electronic device with a search head that is swept over the ground and used to detect buried metal objects such as coins.
3. An electronic device that registers the presence of metal; used, for example, to detect metal weapons or to screen passengers at an airport.
4. An electronic tool used in the food industry to check for the presence of pieces of metal that might have accidentally gotten into food during the processing activities.
2. A lock which has a magnetically coded key about the size of a credit card.
In one version, developed for hotels and motels, the lock code can be changed electronically from a central console, or a physical control panel on a computer or electronic device, as soon as a guest checks out, with a simultaneous preparation of new coded keys.
2. A technique for preventing the operation of a switch until a specific electrical signal (the unlocking signal) is introduced into circuitry associated with the switch.
Usually, but not necessarily, the unlocking signal is a binary sequence.
