During the pres entation a dual channel FFT-based EMI measurement system is presented. Whi le the first antenna receives the signal of the EUT and the ambient noise\ , the second antenna only receives the ambient noise. By using a wideband LMS filter algorithm it is possible to cancel the ambient noise and show t he EMI of the EUT. Measurement results show that typical ambient noise sig nals can be suppressed and even modulated signals of an EUT that are maske d by ambient noise can be recovered. The system can cancel ambient noise w ith a bandwidth of more than 100 MHz. During the presentation the possibil ity for full compliance testing and the limitations of such a system are d iscussed.</p><br /><br />Agenda: <br /><p class="MsoNormal"><span style="f ont-size: 18.6667px\;"><strong>5:30-6:15: Food/Social</strong></span></p>\ n<p class="MsoNormal"><span style="font-size: 18.6667px\;"><strong>6:15-6: 20 Admin\, call for nomination for officers</strong></span></p>\n<p class= "MsoNormal"><span style="font-size: 18.6667px\;"><strong>6:20: Start of pr esentation</strong></span></p> END:VEVENT END:VCALENDAR
