摘要
从实际应用的要求出发,以IIR数字滤波器的基本理论为依据,按照层次化、模块化、参数化的设计思路,采用VHDL硬件描述语言和原理图两种设计技术进行了IIR陷波滤波器的硬件设计,并在制作的实验电路中进行了实际滤波效果测试,测试结果表明该IIR陷波滤波器具有很好的滤波效果,验证了设计的正确性。
From the request of practical applications, the basic theory of IIR filters is according to. From the clew of implementing a stratified, modularized and parameterized design, the thesis describes the hardware implementation of the IIR notch filter with VHDL and schematic diagram design method. The accomplished design of IIR notch filter is tested in experimental circuit after configured. The experiment result indicates that the design is correct.
