We propose in this paper an original approach to the implementation of the Lagrange Interpolator Filter (LIF) based on the formal power series expansion of the transfer function of the ideal fractional delay digital filter. This approach leads to a different, new, modular and robust algorithm usable for real-time delay-varying applications.
