Abstract: The mechanism analysis of EM radiation about digital ITE, such as computer, is given, and the simulation results of the differential-mode radiation about the rectangular pulse and the common-mode radiation about the tripulse in digital circuit are shown. Then, the radiation emission of PⅢ800 and displayer are measured and analyzed.
