摘要

本文采用遗传算法设计双互补滤波器对，实现了两个全通滤波器的并联。所设计的滤波器具有正则符号数(CSD)系数。提出了一种新的CSD数字恢复技术，以保证算法生成的CSD系数具有预先指定的字长和最大非零位数。

Design of complementary filter pairs with canonical signed-digit coefficients using genetic algorithm

In this paper, a genetic algorithm (GA) is used to design doubly complementary filter pairs, which are realized as a parallel connection of two all-pass filters. The designed filters have canonical signed-digit (CSD) coefficients. A new CSD number restoration technique is proposed to ensure that the algorithm generates CSD coefficients with the pre-specified wordlength and maximum number of non-zero digits.
