包括信号的基本形式,卷积,傅立叶变换,s变换,z变换 不错的源码(Including the basic form of signal, convolution, Fourier transform and s transform, z transformation good source)

对小波系数的s变换,t＋s变换,以及变换系数的规范化,很好的(S transformation of wavelet coefficients, the t + s transformation, as well as the standardization of the transform coefficient, very good)
