摘要 本文给出了一维参数化正交小波滤波器系数向量的解析表达式和它的递推计算公式,还给出了它的一阶变分及二阶变分公式．利用这些结果和最优化方法,给出了FIR正交小波滤波器的逼近和设计问题的优化模型和数值例子． In this paper, we give out the formulation to compute the coefficients of FIR orthogonal wavelet filter and their one-two order derivatives. Some optimum model for filter approximation and correlative numerical examples are present.
