摘要
介绍了紧支小波构造的一般方法,给出了取P(z) 的圆内根时的尺度函数和小波函数的图形及取P(z) 的圆外实根、圆内复根的混合根时的尺度函数和小波函数的图形。
In this article a basic method for constructing compactly supported wavelets is introduced. And the graphs of scaling and wavelet functions using the roots in the circle of P(z) and the mixed root of real roots out of the circle and complex roots in the circle of P(z) is given. It is a further reform of the research on the compactly supported wavelets.
