After filtered, high-frequencyinterference signal is filtered basically. The signal graph can express clear the ergogram.
经过滤波后，高频干扰信号基本被滤去，信号图形能清晰地表达示功图的情况。

The velocity and displacement responses were calculated by a theoretical formula deduced by the authors. The frequency and influencing factor of high-frequencyinterference were analyzed.
基于笔者所建立的理论公式，计算了桩顶的速度和位移响应，对高频干扰频率及其影响因素进行了分析。

In addition, the RFI (radio frequencyinterference) generated may disrupt high speed logic circuits in the system.
