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. Radiography in which the image is detached by direct image converter tubes or by the use of television pickup or electronic scanning, and the resultant signals are amplified and presented for viewing on a kinescope or a recorded television program.
2. The detection, identification, evaluation, and location of foreign, electromagnetic radiations by processing electronic circuits as carried out by aircraft, drones, missiles, earth satellites, or fixed monitoring stations.
It includes both radar reconnaissance and electronic-countermeasure reconnaissance.
2. The process of making a graphical record of a varying quantity or signal (or the result of such a process) by electronic procedures, involving control of an electron beam by electric or magnetic fields, as in a cathode-ray oscillograph, in contrast to light-beam recording.
A solid-state relay (an on/off control device) which uses no moving parts is one example of an electronic relay.
2. A robot whose motions are powered by a direct electronic-current stepper motor; such as, a motor that rotates in small, fixed increments and is used to control the movement of the access arm on a disk drive.
Such dynamic behavior can be simulated by altering circuit gains and reference voltages.2. A procedure that is used for constructing a model of a system by using an analog computer, in which the model is devised at the console by interconnecting components on the basis of analogous configurations with real system elements.
By adjusting circuit gains and reference voltages, dynamic behavior can be generated which corresponds to the desired response, or is recognizable in the real system.
2. A security procedure that is used to restrict access to valuable information.
3. Protection which results from all of the measures designed to prevent unauthorized people access to information of value which might be derived from the possession and study of electromagnetic radiations.
Such a circuit allows a wider range of exposure times, can be more accurate, and, when it is put in a circuit with a photoconductive cell, it permits automatic settings of shutter speeds.
2. An electronic device that indicates the departure of a missile from a predetermined trajectory or the path followed by an object moving through space.
The term sky screen refers to equipment that provides a posiive indication to the military range-safety officer whenever a missile deviates from its planned trajectory or its movement through space.
One sky screen monitors the flight bearing and the other sky screen monitors vertical programming.
2. A contribution to the specific heat of a metal from the motion of conduction electrons.
2. The spectrum resulting from emission or absorption of electromagnetic radiation during changes in the electron configuration of atoms, ions, or molecules, as opposed to vibrational, rotational, fine-structure, or hyperfine spectra.
Changes from the desired speed cause corrective signals to speed up or to slow down the motor.
2. A speedometer in which a transducer sends speed and distance pulses over wires to the speed and mileage indicators, eliminating the need for a mechanical link involving a flexible shaft.
