摘要
与传统的从频域来设计内插滤波器的方法不同,本文从滤波器脉冲响应的方向入手,提出了一种利用曲线拟合设计性能较高的内插滤波器的新方法,从而克服了传统方法利用穷搜索寻找最佳系数花费时间过长的缺点。这种方法尤其适用于内插滤波器系数较多或者需要的精度较高的情况。
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.
