摘要
本文提出了频率特性有间断点的滤波器全相位设计方法,给出全相位数字滤波器与原FIR滤波器的结构,推导出了全相位数字滤波器的内插函数,并用实验证明全相位陷波器具有良好的陷波频率特性。
This paper introduces a design method of all phase filter with discontinuous frequency characteristic, the structure of all phase digital filter and customary filter is given and the formula of all phase digital filter＇s interpolation function is deduced, The experiment proves that the all phase notch filter has good notch frequency performance.
