Simplified all-phase filtering structure with frequency response controlled
Huang Xiang · Sciencepaper Online · 2009
To reduce the computation complexity of filtering,two sets of simplified equivalent structure for all-phase filtering is presented.And theoretic deduction verifies these two simplified structures’equivalence to the original classical filtering structure in frequency domain.Simulation proves that not only the novel filter’s frequency response can be controlled conveniently,but also the transfer characteristic behaves excellent.And quantity analysis shows that the multiplication can be approximately saved 50%,so the proposed filtering structures are applicable.
