Fields in Electronics

 

Automotive Electronics

Electronics are used to control and monitor engine functions, control-braking systems, provide entertainment, and display useful information to the driver.  Electrical sensors are used in fuel systems to obtain fuel/air mixture.  Cruise control and on-board monitoring computer systems require an understanding of electronic concepts. 

 

Avionic Electronics

Avionic electronics is concerned with electrical, communications, instrumentation, computer, military and industrial control/sensor applications in all types of aviation equipment. 

 

Communications Electronics

Electronics communications encompasses a wide range of specialized fields.  Specific interests include space and satellite communications, commercial radio and television, citizen's band and amateur radio applications.  Additional areas are data communications, navigation systems, radar, telephone systems, military applications and specialized radio applications such as police, aircraft, and so on. Other communication applications include music concert and stage special effects, music recording and synthesizing. Communication networks are emphasized; these systems include fiber-optic technology and satellite communication links.  The new technology of wireless communication is becoming a reality.  Devices like pagers, cordless and cellular telephones, and wireless computer network systems are influencing our everyday applications.

 

Computer Electronics

The digital computer’s applications are broad and diverse.  For example, computers are used for record keeping, accounting, payrolls, to perform complex calculations, to control and monitor manufacturing processes.  Communications, navigation, medical, military, and home uses are additional applications of computer electronics.  Technicians install and maintain computer network systems. Knowledge of both hardware and software applications is needed. 

 

Consumer Electronics

Consumer electronics include servicing and repairing televisions, videocassette recorders (VCRs), CD players, and sound systems.  Repair technician’s work with appliances such as microwave ovens, washers, dryers, and home security and entertainment applications.  Other repair areas include video games, telephone and answering applications, environmental monitoring, home satellite receivers, cameras, home video applications, and other consumer electronics.

 

Industrial Electronics

Industrial technicians maintain and troubleshoot electronic and electromechanical systems used in the testing and manufacturing of products.  Industrial techs are employed extensively in the control of manufacturing processes.  Areas of concern include control of ingredient mixes, operation of machine tools, product inspection, control and distribution of power, and waste treatment applications. Industrial technicians also work with programmable controllers, robots, computer-aided-design (CAD), computer-integrated manufacturing (CIM), automatic guided vehicle (AGV), plus many other industrial environment sensors and control devices.

 

Instrumentation Electronics

Instrumentation electronic applications include data acquisition and analysis, computer modeling and numerical problem solving.  The instrumentation field often overlaps into other fields because of the demand for calibrated instruments, gauges, and control devices.  Instrumentation technicians work with closed-loop applications, data acquisition, and logical control systems. 

 

Medical Electronics

Electrical devices are finding their way into the medical field.  The electrocardiograph (ECG) is used for the diagnosis of heart and other circulatory ailments.  The diagnostic sounder uses ultrasonic sound waves for various procedures in neurology.  The electroencephalograph (EEG) is used to record the electrical activities of the brain.  Electronic instruments are used extensively in intensive-care facilities.  Monitoring equipment to monitor heart rate, pulse, body temperature, respiration, and blood pressure must be calibrated and maintained.  Technicians familiar with the operation of CAT and MRI diagnostic equipment are necessary to keep the equipment operating properly.  Therapy applications that use lasers, ultrasound, and electronic acupuncture equipment - must be calibrated and maintained to operate correctly.  Additional equipment used for rehabilitation, including pacemakers, biofeedback, artificial limbs, and hearing aids, must be properly maintained.

 

Military Electronics

Military electronics includes troubleshooting walkie-talkies, satellite communications, and global positioning satellites.  Additional areas that use electronics include electronic equipment for smart weapons, laser-guided missiles, shipboard communications, and satellite surveillance.  Extensive expansion of network technology is being rapidly implemented in military applications.

 

Radio & Television Broadcast Electronics

Broadcast electronic technicians install, repair, and maintenance the electronics equipment that is used in live commercial radio and television broadcast stations.  The technicians also work with audio mixers and modulating equipment applications.  Transmitter maintenance, which includes high-power oscillators and broadcast antennas, are also the responsibility of a broadcast technician.
