Abstract

The article concerns problems of electromagnetic compatibility of contemporary IT devices. Particular attention was paid to undesirable emissions, which are by products generated unintentionally during realization of basic functions of device. In the article the methodology of measuring conducted emission on supply terminals of IT devices according to the PN-EN 55022:2006 standard in the frequency range from 0,15MHz to 30MHz has been presented as well as the methodology of measuring radiated emissivity of IT devices in accordance with the norm: PN-EN 55022:2006 in the frequency range from 30MHz to 6000MHz. Also the results of measurements conducted on particular number of central processing units have been demonstrated along with keyboards and mice produced in the years 2007 - 2009 and next their analysis has been made.
