Abstract
A function generator that converts a discrete time signal to its interpolation by a quadratic spline function with no phase distortions is described. The generator synthesizes the output as a linear combination of B-spline functions generated coherently and continuously. The method reduces the total scale of the circuitry and improves the accuracy in the final output waveform. An implementation of the spline function generator is described
