| 摘 要： | 本文将分数阶的低通滤波器的传递函数通式近似设计为Butterworth滤波器，在确定阶数与截止频率之后计算得到传递函数的系数.继而，本文通过该传递函数设计电路，进行仿真并电路实现.本文设计的电路在任意阶数下都只需要修改小部分元件便可得到预计截止频率，具有很强的灵活性，方便对比研究各阶分数滤波器.

| Abstract: | the transfer function of the fractional low-pass filter is approximated as a Butterworth filter.The coefficients of the transfer function are calculated after determining the order and the cutoff frequency.Then,the circuit design,simulation and circuit implementation are based on the transfer function.In this paper,the circuit in any order can be implemented by changing few parts of the circuit which has a strong flexibility. |
