摘　　要：针对双二次型低通滤波器设计过程的要点和注意事项,完整地介绍了双二次型低通滤波器的设计方案,通过归一化算法,结合EDA软件仿真,给出了双二次型低通滤波器的通用设计方法和优化方法。结合实际应用案例详细阐述了在Proteus中如何对所设计的滤波器进行仿真和测试。测试结果表明,使用该方法设计的低通滤波器性能稳定、设计难度小,成本低的优点,为低通滤波器的设计提供了一个新思路。The design scheme of biquadratic low-passed filter is introduced completely,especially the highlights and the matters needing attention in the filter design. The design method and optimization method of the low-passed filter are given in this paper by using the normalization algorithm and simulation with EDA software. The methods to simulate and test the low-passed filter by Proteus are elaborated in combination with actual application case. The testing result shows that the biquadratic low-passed filter designed with the method works steady,and has the advantages of less difficulty and low cost. This method is also provides a new idea for low-passed filter design.
