Fast Design Algorithms for FIR Notch Filters
Based on symmetry of the maximally flat frequency response of a FIR notch filter the new design procedure is developed. The closed form solution provides direct computation of the frequency response, recursive computation of the impulse response coefficients, simple windowing technique, and an access to new implementation. Several examples are included. INTRODUCTION In order to remove a single ...
متن کاملDesign of Linear-phase Fir Filters with Minimum Hamming Distance
In this paper a new approach for the design of linear phase FIR filters with discrete coefficients is proposed. A mixed integer linear programming (MILP) problem is formulated that minimizes the total Hamming distance between the adjacent coefficients, i.e., the number of bit switches of the coefficients. The Hamming distance between the coefficients is a good measure of the power consumption, ...
متن کاملDesign of Non-Uniformly Spaced Linear Phase FIR Filters Using Mixed Integer Linear Programming
In this correspondence, a more efficient algorithm thanthe overlap-and-add (or overlap-and-save) method is deveIoped forquickly computing the convolution involving very long impulse response.By dividing the input and the impulse response into segments ofproper length, the algorithm requires fewer multiplications than theexisting methods and therefore reduces the complexity o...
متن کاملDesign of Reduced Complexity Linear-phase Polyphase Fir Filters Using Mixed Integer Linear Programming
In this work a mixed integer linear programming (MILP) formulation for the design of a class of linear-phase FIR filters are presented. The formulation can be solved using general purpose MILP solvers to obtain filter implementation with a minimum number of signed-power-of-two (SPT) terms given a filter specification. The filter structures considered are based on reduced complexity polyphase de...
متن کاملA Multiplierless Structure for Maximally Flat Linear Phase FIR Filters
A novel multiplierless structure for maximally flat linear phase FIR digital filters is proposed. The structure is based on a recursive evaluation technique for Bernstein polynomials. It consists of identical multiplierless building blocks connected in a regular fashion.
