摘　　要：针对高阶Butterworth低通滤波器实现复杂问题,提出了一种快速设计高阶Butterworth低通滤波电路的方法。推导出奇数阶Butterworth低通滤波电路是1个一阶Butterworth低通滤波电路和若干个二阶滤波网络的级联,偶数阶Butterworth低通滤波电路是若干个二阶滤波网络的级联,给出设计高阶Butterworth低通滤波电路元件参数的计算公式,利用这些公式可简单快速地设计出满足技术要求的任意高阶Butterworth低通滤波电路。It is very complicated to realize the high order Butterworth low pass filter, so puts forth a quick design method to implement this kind of filter. It is deduced that the odd high paper order Butterworth low pass electrical filter can be cascaded by one 1 st order Butterworth low pass electrical filter and some 2nd electrical filters. It is also deduced that the even high order Butterwoth low pass electrical filter can be cascaded by some 2nd electrical filters. The formula for calculating the component parameters of the high order Butterworth low pass electrical filter are given. With the help of these formula, the above- said filter can be designed quickly.
