摘　　要：传统滤波器设计过程中存在许多不足之处,如复杂的数值计算、参数值可选择的分布区间较小、参数之间的耦合度较高等问题,提出基于Matlab编程将滤波硬件电路参数计算程序化的方法,对不同的环境要求只需改变相应的输入参数即可快速设计出满足期望指标的模拟滤波器。该方法具有简便直观、精度高等优点,且解决了大量繁琐的计算问题、提高了设计效率。最后通过实例验证了此方法的可行性和实用性,对今后有源带通滤波器的设计具有很好的实际意义。There are a lot of inadequacies in the traditional filter design process,such as complex numerical calculations,selected distribution range of the parameters is small,degree of coupling between parameters is high.This article proposes a method based on Matlab.An analog filter in different environments is designed quickly to meet the change input parameters.This method can calculate circuit parameter using Matlab program,and has intuitive and accurate advantages.It solves tedious computational problem in the design process.The efficiency and flexibility of design is improved significantly.Finally,an example is given in the paper verify that this method is feasible and available,moreover is meaningful to design active analog band-pass filter.
