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.
It was used in early electronic circuitry to control a flow of electrons.2. An electronic instrument which consists, typically, of a sealed glass bulb containing two or more electrodes.
It is used to generate, to amplify, and to rectify electric oscillations and alternating currents.
2. Altering the frequency of a reflex klystron oscillator by changing the repeller voltage.
3. Frequency changing in a transmitter or receiver by changing a control voltage rather than the circuit components.
A klystron is a term referring to an electron tube used to generate or to amplify electromagnetic radiation in the microwave region by velocity modulation.
2. The process of recording color signals onto photographic film as black and white coded images.
3. The recording of black and white or color television visual signals on a reel of photographic film including coded black and white images.
2. A small television camera which replaces the reflex viewfinder of a motion picture camera.
Such a viewfinder allows the image being photographed to be viewed simultaneously by several people because the TV image may be transmitted to several receivers.
2. A type of regulator that uses all solid state devices to perform the regulatory functions.
2. A voltmeter that uses the rectifying and amplifying properties of electron devices and their associated circuits to secure desired characteristics; such as, high-input impedance, wide-frequency range, crest indications, peak-to-peak indications, and so on.
It is called a "vacuum-tube voltmeter" when its electron devices are vacuum tubes.
2. A division of electronic warfare involving actions ordered by, or under direct control of, an operational commander to search for, intercept, identify, and to locate sources of intentional and unintentional radiated electromagnetic energy for the purpose of immediate threat recognition.
An electronic warfare support that provides information which is required for immediate decisions or actions involving electronic counter measures, electronic counter-countermeasures, avoidance, targeting, homing, warfare operations, and other tactical military employment of forces.
2. Military action involving the use of electromagnetic and directed energy to control electromagnetic spectrum or to attack a military enemy.
Electronic warfare consists of three divisions: electronic attack, electronic protection, and electronic warfare support.3. The use of an electromagnetic spectrum by using devices to attack enemy personnel and equipment or to defend against these procedures and techniques.
4. A military action intended to prevent the use of electromagnetic radiation by hostile forces or to keep and to exploit its use by friendly forces.
Electronic warfare includes electronic countermeasures and counter-countermeasures.
2. A timepiece in which a battery replaces the mainspring, and the semiconductor elements replace the mechanical switching-contact arrangement.
