Abstract:We propose a new design method of FIR filters with discrete coefficients. In the proposed method, the design problem of FIR filters is formulated as Mixed Integer Linear Programming (MILP), which then can be solved by a branch and bound technique. It is possible to obtain the optimal discrete coefficients with desired word-length and flatness constraints, and the optimality of the obtained solution can be guaranteed. Several numerical examples are provided to demonstrate the superior performance of our design … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
