Delta operator-based implementation over the conventional shift operator approach has been applied to the direct form based structure, and the satisfactory performance including low roundoff noise gain and low coefficient sensitivity, has been achieved. However, the approach for delta operator has not been applied into the lattice filter structure. In this paper, a novel lattice filter structure is...
In this paper, a pipelined implementation of a Hessenberg-based input balanced realization is derived, which is realized by placing the delay elements in the lower path and the upper path alternately. The proposed pipelined structure is canonical in the sense that no extra delay is needed. For an Nth order filter, the proposed structure requires 5N −1 multipliers, which has two less multipliers than...
