测定信号 meaning in Chinese

measured signal

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。
