Linear-Phase Sharpening Complementary Filter Pair Using IIR Filters
Dolchai Sookcharoenphol,Shigenori Tomiyama 제어로봇시스템학회 2011 제어로봇시스템학회 국제학술대회 논문집 Vol.2011 No.10
This paper presents a new linear-phase sharpening filter based on two parallel all-pass networks. Each network consists of noncausal and causal IIR filters in cascaded to obtain the linear-phase characteristics. Mostly, a sharpening filter given high attenuation in stop band can be realized utilizing cascade of n time identical IIR filters. However, the overall filter is highly nonlinear-phase characteristic. The new structure gives high sharpening, linear-phase properties type-I and also high efficient of complementary filter pair is presented.
