Hirokazu Tohya, Member (Resources and Environment Protection Research Labs., NEC Corporation) Discrete wavelets transform is widely used for the wave and image analysis. Particularly, multi-resolutional analysis is extremely useful tool for the noise reduction. On the other side, electromagnetic field coming from the printed circuit boards (PCB) is becoming one of the noise sources according to the rising up the operation frequency of central processing unit (CPU). In order to reduce the noise coming from PCB, it is extremely important to grasp the dominant current distributions on the PCB.<br>In the present paper, we apply the discrete wavelets analysis to the noise reduction of the current vector distributing on the PCB. Numerical and practical examples demonstrate that the noise current vectors are dramatically removed by our approach.
