噪声电流
noise current
- 在测试样板和7158型开关卡之间应该使用低噪声同轴电缆，以避免噪声电流。
Low noise coax cables should be used between the test coupons and the Model 7158 CARDS to avoid noise currents. - 根据光接收机前端等效电路模型，建立了噪声系数与等效输入噪声电流谱密度的关系。
Based on the equivalent circuit model of a two-port optical receiver front-end, the relationship between the equivalent input noise current spectral density and the noise figure is analyzed. - 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。
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.
