双线性变换法设计Butterworth滤波器。分别画出滤波前和滤波后的时域图和频谱图。(Bilinear transform design Butterworth filter. Draw the pre-filter and the filtered time-domain and frequency spectrum.)

关于小波包奇异值的程序，很好用的，而且配上了关于小波包奇异性的相关知识！(The program about the singular value of the wavelet packet is very useful, and it is matched with the related knowledge about the singularity of the wavelet packet.)

this code generates random numbers according to different distributions, Gaussian distribution, Rayleigh distribution, Rician and Nakagami, weibull and suzuki model.

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)
