In this paper, a new structure is introduced for the design of variable fractional-delay (VFD) FIR filters. Based on Taylor series expansion of the desired frequency response, an effective structure can be derived. Design example shows that the performance of the proposed system is better or the required number of independent coefficients is less than the existing structures.
