What is EMC ?
EMC(ElectroMagnetic Compatibility):電磁兼容
Ability to operate in, and not overly contribute to, an environment of electromagnetic radiation.
在有電磁輻射的環境中, 設備和系統能正常運行, 不會互相干扰
The Two Aspects of EMC
1. EMI(ElectroMagnetic Interference):電磁干扰
Electromagnetic energy emanating from one device which causes another device to have degraded performance.
從一個設備中發射出的電磁能量會使其它的設備性能降低.
2. EMS(Electromagnetic Susceptibility):抗電磁干扰
Tolerance in the presence of electromagnetic energy(Performance degradation due to electromagnetic energy)
