Electromagnetic compatibility (EMC) refers to the equipment or system in its electromagnetic environment to meet the requirements of the operation and does not produce intolerable electromagnetic interference to any equipment in its environment the ability.
Therefore, EMC includes two requirements: on the one hand, it refers to the normal operation of the equipment in the process of electromagnetic interference in the environment can not exceed a certain limit; (not interfere with other electronic products)
On the other hand, it refers to the apparatus in the environment where the presence of electromagnetic interference with a certain degree of immunity, that is, electromagnetic sensitivity (not interfered with by other electronic products).
