Abstract :
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.
