Design of Finite Word Length Linear-Phase FIR Filters in the Logarithmic Number System Domain
Logarithmic number system (LNS) is an attractive alternative to realize finite-length impulse response filters because of multiplication in the linear domain being only addition in the logarithmic domain. In the literature, linear coefficients are directly replaced by the logarithmic equivalent. In this paper, an approach to directly optimize the finite word length coefficients in the LNS domai...
متن کاملDesign of finite-word-length FIR filters with least-squares error
This paper proposes a new algorithm for designing "nite word length linear-phase FIR "lters. The new algorithm produces "nite-precision least-squares error (LSE) solutions with much reduced search time than the brute-force full search algorithm. It is di!erent from the full search algorithm that tries all possible combinations directly. The new algorithm utilizes geometric properties of a hyper...
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 optimum high-order finite-wordlength digital FIR filters with linear phase
A novel iterative quantization procedure for the design of finite wordlength linear phase FIR filters of high order and minimum frequency domain error is proposed: a one by one increased number of filter coefficients is quantized where the augmented frequency domain error is re-minimized in each case. This new approach achieves a smaller frequency domain error than rounding of the optimal non-q...
