break signal meaning in Chinese
断信号
Examples
- Gets or sets the break signal state
获取或设置中断信号状态。 - The break signal state occurs when a transmission is suspended and the line is placed in a break state all low , no stop bit until released
当传输被挂起并且线路被置于中断状态（均为低，无停止位）时，中断信号状态发生且直到此中断信号状态被释放时才停止。 - Chapter 2 is devoted to compare wavelet analysis and fourier analysis . the features of each element in wavelet family will be studied , and the criteria in choosing the wavelet function for different purposes will be outlined . an example is given to show how to use the relationship between the wavelet coefficient modules and the broken signal to achieve fault diagnosis
第二章简要介绍了小波分析和傅里叶分析的差异，并分析了matlab所提供的小波函数的特点，探讨了小波基选择的标准，最后用实例说明了利用小波变换后的系数模值和信号突变的关系来诊断故障。 - Lacking of space locality in time domain , fourier analysis can only make certain of the integral singularity of a function or signal . as a result ; it is difficult to detect the spatial position and distribution of broken signal by fourier analysis . wavelet analysis has the characteristic of spatial locality , and its wideness in both windows of the time and the frequency can be adjusted , so it can analyze the details of a signal
小波分析优于傅里叶之处在于，小波分析在时域和频域同时具有良好的局部化性质，因为小波函数是紧支集，而三角正、余弦的区间是无穷区间，所以小波变换可以对高频成分采用逐渐精细的时域或空间域取代步长，从而可以聚焦到对象的任意细节。 - Lacking of space locality in time domain , fourier analysis can only make certain of the integral singularity of a function or signal . as a result , it is difficult to detect the spatial position and distribution of broken signal by fourier analysis . wavelet analysis has the characteristic of spatial locality , and its wideness in both windows of the time and the frequency can be adjusted , so it can analyze the details of a signal
经典的fourier变换把信号按三角正、余弦基展开，将任意函数表示为具有不同频率的谐波函数的线性迭加，能较好地刻划信号的频率特性，但它在时空域上无任何分辨，不能作局部分析，这在理论和应用上都带来了许多不便。
