cut off frequency meaning in Chinese
截止频率
Examples
- But it was only about 0 . 3 when the cut off frequency of target signals increased to 0 . 4 hz
相干函数也表明在小于0 . 1赫兹时有较高的值。 - From simulation we can see that the lower of the digital low pass filter ' s cut off frequency , the smaller of the instruction current ' s aberration . experience from foreign country show that active power filter has good application foreground . so its research and application is very important in the future
本文还重点讨论了数字低通滤波器的设计及其截至频率对指令电流精度的影响，通过仿真得出结论：数字低通滤波器的截止频率越低，基波有功电流的畸变就越小，从而基波有功电流减去负载电流求得的指令电流的误差也越小。 - Four white noises which have different cut off frequency were used as random control signal ( target signal ) in the simulation experiment . the results indicated that the correlation between the measured velocities and target signals decreased when the cut off frequency of the target signal increased . the correlation between the measured velocities and the target signals with cut off frequency of 0 . 1 hz was 0 . 85 ~ 0 . 9
在风洞中利用截断频率分别是0 . 1赫兹、 0 . 15赫兹、 0 . 2赫兹和0 . 4赫兹的水平谱原始信号进行模拟实验，结果表明随着原始信号的截断频率增大，实验风速信号与原始信号的相关系数逐渐变小，当原始信号截断频率为0 . 1赫兹时，相关系数在0 . 85 0 . 9之间，而当截断频率为0 . 4赫兹时相关系数仅为0 . 3左右。 - The simulation results prove that active power filter can not only eliminate harmonic current effectively , but also have well dynamic compensation characteristics . designing of digital low pass filter and the effect of its cut off frequency on precision of instruction current are discussed in this paper
仿真结果证明，有源电力滤波器对于三相平衡负载或三相不平衡负载的谐波电流都起到了很好的补偿作用；同时当负载电流突变时，有源电力滤波器具有良好的动态补偿特性。
