基于电网谐波的低通滤波器的设计

Design of low pass filters based on power system's harmonics

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2种设计技术进行了IIR低通滤波器的硬件设计,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低通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,based on theory of IIR filters and in view of implementing a stratified, modularized and parameterized design, the thesis describes the hardware implementation of the IIR low-pass filter with VHDL and schematic diagram design method. The accompllshed design of IIR low-pass filter is tested in experimental circuit after configured. The experiment result indicates that the design is correct.
