摘要
本文提出了一种设计具有等波纹对数幅度响应的线性相位ＦＩＲ数字滤波器的方法，该设计方法以多次交换算法为基础。在给定通带与阻带误差比、通带误差和阻带误差三种情况下讨论该设计方法。介绍几个低通对数ＦＩＲ滤波器的设计例子，来说明该设计方法的效率。
An efficient design method for linear phase FIR filter with equiripple Log magnitude response is presentedin this paper. The design procedure is based on the multiple exchange algorithm. The design algorithm is discussed in threecases where the pass-band and stop-band error ratio, or the pass-band error,or stop-band error are specified. Several designexamples for low-pass Log FIR filters are presented to demonstrate the effectiveness of the proposed procedure.
