Разработка и исследование нерекурсивных цифровых фильтров без умножений

Abstract

This paper describes a new method for design digital filters. This technique presents possibility of special class synthesis of arbitrary order Finite Impulse Response (FIR) filters implemented without multiplications. Synthesized filters have unified structure components and any order filters provide wide dynamic range of processing data, and also have high computational efficiency and increase of the computation speed. The filter’s structure has a great influence on main parameters of synthesized filter. As a result methods of synthesis filters without multiplications with optimal parameters are given. Recommendations about a choice of the best technique of synthesis of filters without multiplications are made. It is given an example receiving structure of non-recursive lowpass digital filter without multiplications on the basis of its magnitude response and impulse response. Necessary recommendations about designing of non-recursive digital filters without multiplications effective by criterion of a minimum of hardware and computing expenses are formulated.
