设计了一个切比雪夫低通滤波器，切比雪夫滤波器的通带内有纹波，阻带内衰减快，它是以通带内的波纹换取截止频率处的最大衰减。波纹越大，截止频率处的衰减越大。该设计方案能达到较好的滤波效果，并用电路仿真软件对其进行了仿真，仿真结果非常接近于理想滤波器的频率响应曲线。
設計瞭一箇切比雪伕低通濾波器，切比雪伕濾波器的通帶內有紋波，阻帶內衰減快，它是以通帶內的波紋換取截止頻率處的最大衰減。波紋越大，截止頻率處的衰減越大。該設計方案能達到較好的濾波效果，併用電路倣真軟件對其進行瞭倣真，倣真結果非常接近于理想濾波器的頻率響應麯線。

Proposed a design of Chebyshev low-pass filter, the Chebyshev filter has ripple in passband, attenuates fast in stop-band, it attaints the maximum attenuation at the cutoff frequency in charge of the ripple in passband .The ripple gre-ater, the attenuation at the cut-off frequency is greater. The design scheme can achieve better filtering effect, simulation has done with the circuit simulation software, the simulation results are very close to the ideal filter frequency response curve.
