Construction of EMC Forecast Model with Network Theory

The purpose of EMC forecast is to forecast the EMC condition of systems or equipments,and solve the EMC problems during designing and testing.As a recult,the reliability will be enhanced and the cost will be reduced.In setting up networks,attention must be paid to EMC problems.Otherwise,the subsystems will interfere with others or be disturbed by others,and the network functions will be affected.In this paper,a model used to predict the EMC condition among systems is introduced.As network theory and spectrum concept are used to solve EMC forecast problem,the hypostasis of interference will be unmasked.In this way,the EMC forecast model will be visualized,simple and can be actualized easily by computer.
