Abstract
In this paper, design of variable fractional delay filter is investigated. DFT Interpolation method is utilized, with suitable index mapping to design a VFD FIR filter. Design examples are demonstrated to evaluate the effectiveness of the designed filter with the help of magnitude, group delay & relative error. Results of designed VFD FIR Filter are within acceptable limits over a wide range of frequency. Finally, the realization of VFD FIR filter is proposed.
