The FCC regulates only electromagnetic interference. Electromagnetic Interference is divided into two types

The following ways:

1. Conduction interference

propagates through power lines, signal lines, and other conductors, and the FCC requires frequencies from **0Khz to
At *0Mhz, the interference at low frequency is mostly conducted interference.

2. Radiation Emission

Spread through space. From *0Mhz to 1Ghz, most of the interference at high frequency is radiation interference.
Usually, both kinds of interference can coexist.

3. Antenna disturbance.
This applies to devices with external antennas. Such as TV.
