摘要
在小波理论中,精度或逼近阶是刻划尺度函数最重要的特性之一。就M进制多小波的尺度函数在时域里逼近阶条件进行研究,并给出了尺度函数具有逼近阶m的充分必要条件。
On the wavelet analysis theory, accuracy or approximation order is one of very important properties which characterizes the scale function. The approximation order of M band scale function is investigated on the time domain. Meanwhile, the sufficient and necessary conditions which the scale function provides the approximation order m are given.
