设计了一个巴特沃斯低通滤波器，并用电路仿真软件对其进行了仿真，幅频特性和相频特性较好，通带内频率特性平坦，且不存在波浪起伏现象，阻带内的曲线缓缓变化到零，所得指标能满足要求，能达到较好的滤波效果。
設計瞭一箇巴特沃斯低通濾波器，併用電路倣真軟件對其進行瞭倣真，幅頻特性和相頻特性較好，通帶內頻率特性平坦，且不存在波浪起伏現象，阻帶內的麯線緩緩變化到零，所得指標能滿足要求，能達到較好的濾波效果。

Proposed a design of Butterworth low pass filter, and simulated the circuit with the simulation software. The ampli-tude-frequency characteristic and phase frequency characteristics are perfect, within the pass-band frequency characteristic is flat, and there are no wave fluctuations, the curve changes slowly to zero inside the stop band, the index can meet the require-ments, can achieve better filtering effect.
