Radio
or TV interference occurs when a high-frequency signal distorts
the incoming signal to the cable or antenna input of televisions and radios.
Cordless telephones can also be affected. The causes of these problems can be
easy to identify. When a common appliance generates electrical noise that interferes
with the TV or radio, it may be easy to match the cause with the problem by
watching to see what is coming on when the interference occurs.
Unfortunately, many of the causes of interference cannot be seen or heard.
Electromagnetic Interference sources may originate inside the home or can result
from certain environmental conditions. Finally, interference can be caused by
activities in a neighbor's home or elsewhere in the electric utility's system.
