Time Delay Interpolation by System Response
Jonah Gamba, Tetsuya Shimamura · 2005
In this letter, we propose a new method of time delay interpolation based on the finite impulse response (FIR) filter coef- ficient ratios and derived from the Lagrange interpolation coeffi- cients. 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. Index Terms—Coefficient ratios, Lagrange interpolation, time delay.
