在电子电路中滤波器的应用越来越广泛,带通滤波器是滤波器中应用最多的一种.文章设计的四阶RC有源带通滤波器元件少,制作方便,并对设计的带通滤波器的传递函数及中心频率等特性参数进行了详细的推导,由幅频特性测试得到实测的中心频率误差较小,在通带内具有均匀而稳定的增益.

It is getting far and wide using the filters in the electronic circuit. Using the band-pass filters is the most in using the filters. This paper proposes making RC four-stage active band-pass filters with less elements and its pertaining convenient produltion method,and the transfer function and centre frequency parameter are deduced in particular. The experiment error of the amplitude frequency characteristic is less and there are steady and uniform gain in the bandwidth.
