摘要
提出了一种利用频域非均匀抽样原理设计线性相位滤波器的新方法,此方法运用频率特性的最佳曲线拟合手段,只需给出理想频中特性上的一些特征样本点的值,便能一次设计出具有最优特性的线性FIR滤波器。此方法允许在设定了时域样本点数后随意调整频域样本,点的数量和位置,使滤波器的设计变得十分直观、灵活、简单。
This paper presents a new design method for the FIR linear phasic digital filters by using the unequal sampling theory in the frequency domain. Offering some sampling data of ideal amplititude-equency distribution. The su- perexcellent FIR linear phasic-frequency digital fiters are designed. The amount of these sampling data and frequence positions of these sampling data be flexibly adjusted, and the design is easy, simple, and flexible.
