In the design of filter, especially for the real time signal processing, the demand on the filter performance is not as high as that on the filtervelocity.
在滤波器设计中,特别是实时信号处理场合,有时对滤波器的性能要求并不高,但对处理速度要求高。

Then, the test equipment and experiment is introduced. Through experiment, we get the relation between velocity and filter pressure drop.
介绍了试验设备及测试方法,通过试验得出过滤风速和压力损失变化关系。

In medical Doppler ultrasound systems, a high-pass filter is usually employed to remove wall clutter components which may also remove the information of the low velocity blood flow.
