从等距变换看窗口 Fourier 变换与小波变换

Viewing Windows Fourier Transforms and Wavelet Transforms From Equidistant Transformation

据等距变换的观点，对窗口Ｆｏｕｒｉｅｒ变换与小波变换的定义进行了调整，从中可得到这些变换的演化过程，并得到了其逆变换．此外，讨论了等距变换的基本条件，根据这条件也可以发现和构造新的数学变换．

With the help of equidistant transformation,definitions of window Fourier transforms and wavelet transforms are studied,thereby inverse form of them are easily defined.Equidistant condition is the basis of mathematical transformation,based on which many new mathematical transformation can be found and constructed.
