In this paper, a novel lattice network-based structure is derived for a canonic realization of recursive digital filters. For an Nth order filter, unlike the existing lattice structures the proposed structure has 2N free parameters that can be used to improve the structure properties. The relationship between the transfer function coefficients of the filters and the parameters of the proposed structure...
The excellent finite wordlength property of the lattice digital filter is well known. The four-multiplier normalized lattice, with signal power at all delay elements normalized to unity, has particular advantage in its overflow property. However, when used to implement an Nth order digital filter, the normalized lattice implementation requires 5N +1 multipliers. In this paper, we present a novel lattice...
