摘要

多分辨分析是Ｍａｌｌａｔ为各领域应用的子波变换建立起的统一的数学框架．本文引进基函数的频宽和时宽概念，使各种变换下的频率分辨率和时间分辨率特性一目了然；在塔形算法中，如果应用规范正交基作分解，则可使信号分析和综合框图具有完全对称的形式

Abstract

Two comments are involved: （1）To discribe the frequency and time resolution

theidea of band-width and time-interval of a transform basis function is introduced; （2）Based on theorthonomal bases decomposition of a signal

the block diagram of multiresolution pyramid given byS. Mallat has been modified

so that the perfect symmetry is achieved.
