A Model of Signals of Side Electromagnetic Radiation of Video Interfaces

Energy measurement of side electromagnetic radiation signals is an important task in addressing issues of electromagnetic compatibility and information security. When constructing video systems of computer equipment, parallel transmission lines are used, side electromagnetic radiations from which interact. The article presents the characteristics of circuit realization of video systems and radiation models considering them. In addition, we present a model of information signals of video interfaces, which takes into account the compensatory properties of differential lines in a video system with a DVI interface.
