小波包提取滚动轴承故障能量特征的matlab程序，大家只要把采集的滚动轴承振动信号数据放入程序中即可使用，希望对大家有所帮助。(Bearing Fault wavelet packet energy feature extraction matlab program, we just put a rolling bearing vibration signal collected data into the program to use, we want to help.)

基于DD算法的先验信噪比估计的维纳语音降噪完整程序，包括语音分帧，动态信噪比估计,噪声估计更新和帧的重构。很完整。(DD algorithm based on a priori signal to noise ratio is estimated that the integrity of the process noise reduction Wiener voice, including voice sub-frame, dynamic signal to noise ratio estimation, noise estimation and frame reconstruction update. Complete. I hope to share together.谢谢. Small text.)

Pass the specification values to the object rather than accepting the default values for N, Fc1, and Fc2. Include the sampling frequency Fs as the final input argument. Design the filter and plot the results.
