摘要

本文提出了一种求实线性相位FIR滤波器零点的新方法。利用z变换的性质和对这类滤波器零点位置的约束来减少零点的搜索空间。然后，将获得的零点信息用于WDK公式中，以获得更准确和精确的零点位置。仿真结果验证了该方法的有效性。

Finding zeros for linear phase FIR filters

This paper presents a new technique to find zeros of a real, linear phase, FIR filter. Properties of Z-transform and constraints on location of zeros for this type of filter have been used to reduce search space for zeros. Furthermore, the obtained information on zeros is subsequently used in WDK formulas to obtain more accurate and precise location of zeros. Simulation results validating the proposed technique are also presented.
