    Wiring categories: conducted interference and radiated interference. Conducted interference is the interference transmitted by conductor. Therefore, any conductors (such as wire, transmission line, inductor, capacitor and so on) are the transmission channels of the interference. Radiated interference is the interference transmitted in electromagnetic wave, and the energy is inverse proportional to the square of distance.
