y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level It returns the matrix of all decompositions and the final approximations. Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes. For other wavelets, the filter values alone can be changed or WFILTERS can be used. The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author. Example: clear all t=[0:0.0003:8*pi] x=sin(5000*t)+sin(1000*t) x=x(1:2^16) level=5 Fs=1/0.003 d2wavelet(x,Fs,level) Thanks for Downloading. Don t forget to rate or comment.

时频分析中的cohen类中最基本的双线性时频分布式wigner-ville分布，由于在该分布中不含窗函数，因此避免了短时窗傅里叶变换时间分辨率、频率分辨率相互牵制的矛盾(Time-frequency analysis of the Cohen class of bilinear time-frequency distribution is the most basic Wigner-Ville distribution, because the function in the distribution is not included in the window, so as to avoid the contradiction of short-time window Fourier transform time resolution, frequency resolution of each other)
