초록

본 논문에서는 IIR 필터의 임계 경로를 줄이기 위하여 제한된 Remez exchange 알고리즘을 제안하였다. 제안된 알고리즘은 Remez exchange 알고리즘과 최소 자승법을 이용하였다. IIR 필터 구현 예제에서 제안된 방법이 속도를 최대 20% 증가시킴을 보였다.

In this paper, constrained Remez exchange algorithm is proposed to reduce the critical path of an IIR filter. The proposed algorithm is based on Remez exchange algorithm and least squares method. By IIR filter design examples, it is shown that the proposed method can maximally increase speed by 20%.
