The Personal Computer System is a kind of electromagnetic equipment. And it is composed of many independent components and subsystems. Thus, the electromagnetic radiation from the computer system is contributed by the components and subsystems together. So far, in many existing documents, the computer is considered as a whole for it's radiating characteristics. But we study the computer's radiating characteristics by analyzing the circuit configuration of its differential constituted parts. In my thesis, the study starts from analyzing different kinds of signal's production and flowing paths in the computer system. On the basis of this, the possible radiating sources of the computer's differential parts are predicted and measured. Furthermore, we compare the theoretical analyzing results with measured ones. As a result, we get more knowledge about the electromagnetic radiating mechanism of different components in computer system.In addition, some effort on experiments and theoretical analysis is made to decrease the magnitude of electromagnetic radiation from computer. It shows that the effect of radiation is obviously reduced.
