Definitions and Descriptions
Energy composed of electric and magnetic fields that travels at the speed of light in free space. Natural sources are the sun, stars, and lightning. Artificial sources include lasers, electronic circuits, radio transmitters and power transmission lines.
Any electronic signal present other than the desired signal (Noise). EMI is everywhere and it affects our equipment, business atmospheres, and even our health. As power densities and communication speeds increase in new systems, EMI is created in normally compatible situations.
Electronic equipment functioning properly in intended environments. Compatible devices are not affected by external electromagnetic noise sources and are not sources of EMI to the surrounding environment.
A cell phone that produces unwanted echoes is NOT compatible. A radio tower is an intentional radiator that may cause effects on other equipment such as personal communication devices. Further, unintentional radiators can cause EMI. For example, EMI can be created and experienced by personal computers, wireless networks, and printers.
