Abstract

Test for complying with electromagnetic interference (EMI) emission limits is usually carried out during the product design. A PC-based EMI automatic measurement and filter design system for telecommunications power supplies is proposed. The effort of suppressing EMI emission is greatly reduced by the fast computing speed and the friendly man-machine interface of the PC. The developed system can be an effective noise diagnosis and filter design tool. Not only the design process is speeded up, but also the acceptability of the designers can be enhanced.
