2차 직접형 전역 통과 필터와 유한 임펄스 응답(FIR) 필터의 캐스케이드를 사용하여 구현된 적응형 무한 임펄스 응답(IIR) 디지털 필터는 극이 미지 시스템의 극으로 수렴하는 특성을 갖습니다. 본 논문에서는 최소 개수의 승수를 갖는 격자 전역통과 필터를 사용하여 적응형 전역통과-FIR 디지털 필터를 구현합니다. 그런 다음 직접 형식 전역 통과 필터를 사용하는 ADF와 비교하여 제안된 적응형 디지털 필터(ADF)의 전체 승수 수를 증가시키지 않는 간단한 적응형 알고리즘을 유도합니다. 제안된 구조와 알고리즘은 ADF의 극점과 알려지지 않은 시스템의 극점의 수렴을 보장하는 일종의 직교성을 나타냅니다. 시뮬레이션 결과는 이러한 수렴을 확인합니다.

Abstract: Adaptive infinite impulse response (IIR) digital filter implemented using a cascade of second order direct form allpass filters and a finite impulse response (FIR) filter, has the property of its poles converging to those of the unknown system. In this paper we implement the adaptive allpass-FIR digital filter using a lattice allpass filter with minimum number of multipliers. We then derive a simple adaptive algorithm, which does not increase the overall number of multipliers of the proposed adaptive digital filter (ADF) in comparison to the ADF that uses the direct form allpass filter. The proposed structure and algorithm exhibit a kind of orthogonality, which ensures convergence of the poles of the ADF to those of the unknown system. Simulation results confirm this convergence.
