An efficient orthogonal digital filter structure with sensitivity analysis
Li Gang · Journal of Circuits and Systems · 2010
In this paper,a novel digital filter structure is derived based on a matrix factorization.This structure is actually an improved version of the one reported in [10] but much simpler for implementation.The performance of such a structure is analyzed by deriving the expression for its sensitivity measure.Simulations shows that the proposed structure has almost the same performance against finite word length errors as the traditional optimal structures but much more efficient for real-time implementation.
