两篇中文论文，详细叙述了Farrow滤波器的设计方式和理论基础，非常实用！(Two Chinese papers, described in detail Farrow filter design methods and theoretical foundation, very useful!)

说明：  关于quartus与modelsim 仿真(about quartus and modelsim simulator)

使用verilog语言完成了基于cordic算法求反正切的计算，精度为8次迭代(Verilog language used to complete based on CORDIC algorithm for arctangent calculation, an accuracy of 8 iterations)

用NiosII实现的数字钟，经过本人测试运行正常，开发环境：QuartusII6.0和NiosII IDE6.0-NiosII achieved with digital clock, after I run the normal tests, development environment: QuartusII6.0 and NiosII IDE6.0

FPGA控制AD逐点采集信号，并将AD转换后的数据串行发送出去。(FPGA to control the signal sampling point by point AD, AD conversion and serial data sent.)

mult,在quartusII中，以模块输入形式，仿真乘法器mult，得到时序图和功能图(a simulation example of mult)
