4.7 Installation Guidline to EMC Compliance
4.7.1 General knowledge of EMC
EMC is the abbreviation of electromagnetic compatibility, which means the device or
system has the ability to work normally in the electromagnetic environment and will not
generate any electromagnetic interference to other equipments.
EMC includes two subjects: electromagnetic interference and electromagnetic
anti-jamming.
According to the transmission mode, Electromagnetic interference can be divided into
two 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.
Three necessary conditions or essentials of electromagnetic interference are:
interference source, transmission channel and sensitive receiver. For customers, the
solution of EMC problem is mainly in transmission channel because of the device
