本程序主要有三部分构成：首先是4个积分器部分，其次是抽取器部分实现32倍抽取，最后组成部分是4个梳状滤波器。该程序结构可节省4个32的延迟单元。-The program has three main parts: First, the integrator part 4, followed by the extraction device to achieve 32 times the extraction part, the final component of the four comb filter. The program structure can save 32 to delay unit 4.
