signal-shield ground的意思|示意

With this shield in place, the noise current generated by the electrostatic voltage source and the coupling capacitance flows through the shield to ground rather than through the signal conductors.

有了这种屏蔽，由静电电压源和耦合电容产生的噪声电流就经过屏蔽流到地，而不再流过信号线。

An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.

对于非平衡式信号线来说，就是一根被屏蔽了的信号线，这个中心信号线传输信号，且相对于地电势。
