摘　　要：滤波技术在通讯和测量等领域有着广泛的应用,滤波器对提高电子系统的性能具有重要作用.但是,由于高阶滤波电路原理复杂、元件参数选择和调试困难等原因,滤波电路综合往往成为电子系统设计的难点之一.在深入讨论二阶ButterworthRC有源滤波器的基础上,提出了四阶椭圆低通滤波器及其优化综合技术,仿真和实验验证了该方法的有效性.Fihering technology has a wide application in the fields of communication and plays an important role in improving the performance of electronic systems. However, due to measurement, it the complexity of t The theory of second-order Butterworth RC active filter and the fourth-order elliptic low-pass filter were discussed, and their integrated optimization techniques were proposed. The effectiveness of the method was verified by simulation and experiments.
