本文提出了基于非理想频响特性的多阻带一维ＦＩＲ数字滤波器的设计新方法，该设计过程简单直观，可消除采用窗函数等常规方法产生的Ｇｉｂｂｓ效应。本文还给出基于多阻带ＦＩＲ数字滤波翼的正弦噪声消除实例。仿真结果表明，本文提出的设计方法是有效的。 In this paper, a new design method of multi-stop band one-dimensional FIR digital filter based on non-ideal frequency response characteristics is proposed. The design process is simple and intuitive, which can eliminate the Gibbs effect generated by conventional methods such as window function. This paper also gives examples of sinusoidal noise cancellation based on multi-stop band FIR digital filter wings. Simulation results show that the proposed design method is effective.
