On the basis of analysis of noise, the noise caused by commonimpedance coupling and its harmfulness are introduced comprehensively. The suppression methods are discussed and analyzed.
在分析噪声的基础上，较全面地介绍了公共阻抗耦合的噪声及其危害，讨论分析了抑制该噪声的方法。

Most line drivers with low differential output impedance will also have inherently low common-mode output impedances, so the low impedance arms of the bridge are almost always at the driver.
