Application of the Genetic Algorithms for ElectromagneticNoise Reduction Traces

随着信息和通信设备的操作速度的增加，从它们的印刷电路板上的迹线发出的它们的电磁噪声引起麻烦的问题。我们应用分段传输线，我们已经提出，这个问题。分段传输线是一种新型的传输线，其结构是用遗传算法确定的。我们可以预期相当大的电磁噪声降低，确保高信号完整性与分段传输线。通过对样机的测试，表明了分段传输线对电磁噪声的抑制和波形畸变的改善是有效的。

As operation speeds of the information and communication devices increase, their electromagnetic noises, which are emitted from traces on their printed circuit boards, causes a troublesome problem. We applied the segmental transmission line, we had proposed already, to this problem. The segmental transmission line is the novel transmission line the structure of which is determined with the genetic algorithms. We can expect considerable electromagnetic noise reduction ensuring high signal integrity with the segmental transmission line. Under the measurements using some prototype boards, we showed that the segmental transmission line is effective to the electromagnetic noise reduction as well as the improvement of the distorted waveforms.
