Measurement of the signal is usually vibration and noise, temperature, pressure, current, voltage, etc to one or more of the signal.

测量的信号通常是振动、噪声、温度、压力、电流、电压等信号中的一种或几种。

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。

All real voltage and current sources contain an internal resistance; therefore, they exhibit Johnson noise.

所有真实的电压源和电流源都具有内阻，所以它们都表现出约翰逊噪声。
