This paper proposes a new method for the design of high-performance interpolation filter using polynomial fit.Different from the traditional method, it designs interpolation filter in temporal response instead of spectral response. It overcomes the disadvantage of exaustive search which requirs too much time to fred the optimal coefficients. In view of many coefficients or high precision, this method is advantageous especially.
