摘要

本文提出了一种设计具有合理分数阶延迟的FIR分数阶延迟滤波器的方法。该方法是基于对FDF的一般多率结构和插值有限脉冲响应(IFIR)结构的使用。结果是具有小通带波纹和宽带宽的单一时不变FIR滤波器。本文对该设计进行了讨论，并通过实例与其他设计方法进行了比较。

One method for FIR fractional delay filter design

This paper presents one method for the design of FIR fractional delay filters (FDF) with a rational fractional delay. The method is based on the use of the general multirate structure for a FDF and the interpolated finite impulse response (IFIR) structure. The result is a single, time invariant FIR filter with small passband ripples and a wide bandwidth. We discuss this design, and, through examples, compare it with other design methods.
