摘要: | 本篇论文研究的主题在找出一串有限长度的正数列,使其频谱能够最佳近似于一个已经给定的非负频谱。文中藉由一个简单的滤波器结构开始,用此滤波器结构所产生的优点,以此优点做为我们寻找正数列的开始。也就是重新改变此滤波器的结构,来获得我们所想要的正数列频谱。 The purpose of this thesis is searching for a finite-length positive sequence so that its spectrum can optimally approximate to a given spectrum. In this text, we begin with a simple filter structure and use the advantage of this filter structure. By using this advantage of the filter structure, we can find a finite-length positive sequence. We change this filter structure slightly to obtain the spectrum of the positive sequence which we want. |
