Abstract
In this letter, we propose a new method of time delay interpolation based on the finite impulse response (FIR) filter coefficient ratios and derived from the Lagrange interpolation coefficients. The proposed method gives an explicit formula for the time delay that requires no frequency-domain transformations, making it suitable for entirely time-domain applications. Simulation results confirm the effectiveness of the proposed method.
