Electronics Today
Businesses and other organizations depend on complex
electronic equipment for a variety of functions. Industrial controls automatically monitor
and direct production processes on the factory floor. Transmitters and antennae provide
communication links for many organizations. Electric power companies use electronic
equipment to operate and control generating plants, substations, and monitoring equipment.
The Federal Government uses radar and missile control systems to provide for the national
defense and to direct commercial air traffic. These complex pieces of electronic equipment
are installed, maintained, and repaired by electrical and electronics installers and
repairers.
