Performance and design of Farrow filter used for arbitrary resampling
F.J. Harris · 2002
The Farrow filter (1988) is a multirate filter structure which offers the option of continuously adjustable resample ratio. This paper presents a derivation of the method proposed by Farrow, and demonstrates the performance and complexity of resampling filters using his technique. The paper also develops some important system options made available to the designer as spin-offs of the derivation.
