设备设计师能通过审慎地选择输入输出级电路的拓扑和共模阻抗来最小化失配或“非平衡”的效应。

Equipment designers can minimize the effects of these mismatches or "unbalances" through judicious choices of input and output stage circuit topologies and common-mode impedances.

有低的差动输出阻抗绝大多数的线路驱动器，同时也固有地有低的共模输出阻抗，这样，低阻抗桥臂几乎无一例外地位于驱动器一侧。

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.
