滤波器群时延,group delay of digital filters
Zero Group Delay filter零群时延滤波器
3)near zero group filter近似零群时延滤波器
4)Filter delay滤波器时延
5)fractional delay filter分数时延滤波器
1.In order to compensate the channel dispersed delay accurately,fractional delay filter(FDF) is introduced.为实现宽带数字阵列各阵元传输时延的精确补偿,引入分数时延滤波器。
6)interpolation delay filters内插时延滤波器
1.This paper investigates the principle of the digital orthogonal transformation based on multiphase filtering,and proved that theinterpolation delay filters could be replaced with branch filters from a multiphase filter according to the theory of multi-sampling rate signal processing.仿真结果表明,所设计的内插时延滤波器的相频特性和幅频特性均满足要求。
