如果所有的措施都不能避免RF干扰进入测试输入端，那么就可能需要在设备的输入通路上进行外部滤波，如图3 - 7所示。
If all else fails to prevent rf interference from being introduced into the input, external filtering of the device input paths may be required, as shown in Figure 3-7.
结果表明，如果设计适当的滤波电感值，本文所述的无源功率因数校正方法可以满足标准所要求的规定。
The results obtained show that the passive approach described here can comply with the required specifications if a proper inductor value of the filter is selected.
在非线性、非高斯条件下进行动基座传递对准，如果采用卡尔曼滤波会出现误差较大甚至发散的问题。

如果在叠加剖面上仍有较强的线性干扰，还要再做一次二维滤波。
The second-pass 2D filtering is necessary when quite strong linear noise still remains on stacked seismic section.
如果相位与频率的变化关系是线性的，那么滤波器仅仅会使信号延时一个常数量。
If the phase and frequency changes in the relationship is linear, then the filter would signal delay is only a constant number.
此外，该器件提供可编程抽取率，而且如果数字FIR滤波器的默认特征不适合应用要求，还可对其进行调整。
In addition the device offers programmable decimation rates and the digital FIR filter can be adjusted if the default characteristics are not appropriate to the application.
