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.
