推荐你看看这篇文章，作者是EMC的资深顾问Keith Armstrong：

在文章的结尾处，作者给出了如下的结论：

Conclusion
Because, as we have seen, EMC and signal integrity are really just two different aspects of the same electronic phenomenon, using good EMC design and PCB layout practices from the start of a new project can help

Achieve signal integrity.
Reduce the number of prototype iterations needed and improve time to market.
Cut unit manufacturing costs.
Lower the risk that modifications made during the product's lifetime may inadvertently cause noncompliance or unreliability.

多么经典的总结。

吃饭和喝水的关系阿！

两者相辅相成，一个问题的不同方面。

谢谢，研究中。
