An L1-Method for the Design of Linear-Phase FIR Digital Filters
This paper considers the design of linear-phase finite impulse response digital filters using an L1 optimality criterion. The motivation for using such filters as well as a mathematical framework for their design is introduced. It is shown that L1 filters possess flat passbands and stopbands while keeping the transition band comparable to that of least-squares filters. The uniqueness of L1-base...
متن کاملAn -Based Method for the Design of 1-D Zero Phase FIR Digital Filters
Finite impulse response (FIR) filters obtained with the classical L2 method have performance that is very sensitive to the form of the ideal response selected for the transition region. It is known that design requirements do not constraint in any way the ideal response inside this region. Most existing techniques utilize this flexibility. By selecting various classes of functions to describe t...
متن کاملDesign of nonlinear phase FIR digital filters using quadratic programming
This paper presents two methods for the design of FIR lters with arbitrary magnitude and phase responses according to a weighted mean squared error criterion with constraints on the resulting magnitude and phase errors. This constrained least square criterion allows for an arbitrary trade-o between pure L2 lters and Chebyshev lters. The resulting nonlinear optimization problem is either convert...
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 1-D Linear-Phase Complex FIR Digital Filters by Genetic Algorithm Approach
-The digital filters with complex coefficients are useful in the application of processing analytic signals and complex envelops. They are also applied in single-sideband modulation systems. The genetic algorithm approach for designing such filters is developed in this paper. It is based on the evolution of real-valued population. The method is also optimal in the least-squares sense. Furthermo...
