CIC滤波器的补偿，适用于抽取内插滤波器的设计

5阶cic滤波器，抽取12倍，的verilog程序，已经通过仿真验证，一、具有很高的速率,5-order CIC filter, collected 12 times the Verilog procedures are by simulation, one with a very high rate

抽取滤波器的matlab源代码实现预仿真，修改参数即可使用-Decimation filter matlab source code to achieve the pre-simulation can be used to modify the parameters
