说明: 此程序给出信号的多分辨率分析(Multiresolution Analysis),即信号的多分辨率分解(Multiresolution Decomposition)方法及应用。该程序是一个多抽样率系统(Multirate System)举例,用M个的滤波器,将信号的频谱等分成M部分,使所得抽样频率降为1/M,然后再依据它们的“重要性”给一不同的bit数,那么所传输的bit流必然会进一步下降,起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their " importance" to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)
