| Research Abstract |
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.
