摘要
本文系统地介绍了离散小波的一种常见形式─调频高斯小波,分析了尺度因子对母小波的影响,分别给出了输入函数和小波函数的离散区间的长度值及如何选取的方法。采用卷积积分法,对一定的输入函数进行了小波变换,给出了程序框图,采用Basic语言,编写了实用程序.
This paper systematically introduces the modulated Gaussian Wavelat-a discrete wavelet, the influence of the scaling parameter a on the mother wavelet (t) is analysed, The length value of the discrete span on the input function and wavelet function is presented and chosed. With the help of convolution integzation, the special input function is transformed by wavelet, program block is given, the useful program is compile with Basic computer language.
