Abstract :
This paper describes a case study covering the evaluation and reduction of the radiated EMI from an 18" liquid crystal display (LCD) monitor. The evaluation was completed in two parts: first potential EMI sources at the printed circuit board (PCB) level were identified, then the EMI antennas driven by these sources were analyzed. Methods for reducing the EMI were described in detail, and where applicable, those modifications were applied. Radiated measurements demonstrate the effectiveness of these recommendations
