查询词典 signal

The detailed coefficients of DWT contain signal and noise. Instead of the soft-thresholding method, SVD is applied to decompose the signal features and noise into different orthogonal subspaces. With the reconstruction of the singular vectors in subspace, the signal features are extracted effectively.

该方法通过对每层小波分解细节系数进行奇异值分解，将其中的信号特征成分和噪声分解到不同的正交子空间中，在子空间中选取集成信号特征成分的奇异值矢量进行重构，从而提取出淹没在细节系数中的有用信号成分，最后进行小波重建，得到降噪信号。

Each signal component will see a different impedance for each signal line to its return path and each signal component may also travel at a different velocity.

正确的翻译应该是：每个信号分量将在每个信号线与它的返回路径间看到不同的阻抗，同时也以不同速度传播。

It produces trigger pulse by comparing the!synchronous signal integral with the phase shift signal,and has the ability of resisting synchronous signal high frequency interference and wave distortion.
