该代码是设计一个48阶FIR滤波器的文档，该设计方案主要运用了数字信号处理VLSI实现中的折叠的方式。-The code is a 48-order FIR filter design document, the main use of the design of VLSI implementation of digital signal processing in the way of folding.

滤波器的verilog代码 主要是对算法的折叠 有原先的4个加法器四个乘法器变成2个加法器两个乘法器-Filter verilog code folding algorithm 4 adder four multipliers into two adders and two multipliers
