Electromagnetic interference - Wikipedia
Electromagnetic interference divides into several categories according to the source and signal characteristics. The origin of interference, often called "noise" in this context, can be human-made (artificial) or natural. Continuous, or continuous wave (CW), interference arises where the source continuously emits at a given range of frequencies.
