Abstract :
As a key component of personal computer, CRT monitor is the major source of compromising emanation. In this paper we design an emission-security standard which determines the allowable range of unwanted radiation emission from an electronic equipment to prevent eavesdropping of information. We assume a model for radiated emission from CRT and the results show that these emissions are approximately 25 decibel upper than proposed standard in VHF/UHF band. Nevertheless they are acceptable in published EMC standards.
