包滤波 meaning in English

packet filtering

The a / d transformation function of pc sound card is used to gather noise signal . wavelet packet filtering algorithm is used to eliminate the noise that is independent of the frequency of rotating and pick up the real vibration
利用计算机声卡的a / d转换功能来采集电动机的噪声信号，应用小波包滤波方法消除与回转频率无关的噪声干扰，提取与转速直接相关的振动信号。
3 . based on the theory of analysis methods which include wavelet , wavelet packet and feedback adaptive kalman filtering , it is put forward a proposition combined with wavelet packet and feedback adaptive kalman filtering , in order to result comparative smooth to the signal tested when it is being relatively steady , and extreme strong traceability goal to the signal tested when it is taking place sudden change
在分析动态小波滤波、小波包滤波和误差反馈式自适应卡尔曼滤波方法的基础上，提出基于小波分析反馈式自适应卡尔曼滤波方法，以实现当测定信号相对平稳时滤波结果较为平滑，而在测定信号发生突变时滤波器又具有极强跟踪能力的目标。
