The Electromagnetic Compatibility Design of Restrained Image Transmission Equipments

Abstract:

In order to improve the quality of image transmission, this paper puts forward a box shielding method that could eliminate electromagnetic interference signal on image transmission equipments. At first, this paper analyzes the shielding effectiveness of electromagnetic interference, selects the qualified shielding material and designs the structure. After that, it analyzes the descending of shielding effectiveness in the operational system, and improves the equipments shielding effectiveness by means of the electromagnetic compatibility design that accords with electromagnetic compatibility norms. At last, through the EMI radiometry, this paper confirms that the equipments are in accordance with the design requirements of electromagnetic compatibility norms.
