presents the configuration, which appently is not in the literature, for perfect signal reconstruction. The sampling of information with FIR filters is very common [1]. The signal reconstruction of a data stream sampled with these filters is typically not analyzed in a simple manner, and the invocation

Finite impulse response (FIR) structures are the most commonly used digital filters and can be found in various areas of everyday life. In this paper we introduce a novel approach to construct and optimize a redundancy-free de-sign of such filter structures. Relying on attribute grammars

Abstract: Douglas-firs from 91 seed sources in North America were evaluated after 5 and 6 years in 15 common-garden tests in the mountainous regions of northwest and north central Spain. Analyses of tallest trees showed that most of the sources of highest potential for reforestation in Spain

In this paper we develop a general and very simple construction for complete orthonormal bases for system identification. This construction provides a unifying formulation of all known orthonormal bases since the common FIR and recently popular Laguerre and Kautz model structures are restrictive

-objective system identi#cation based on constrained optimization is suggested, and here we formalize the method for the identi#cation of FIR models. Particular attention is paid to the analysis and selection of tradeo#s between con#icting objectives and constraints. Keywords: Optimization, Parameter Estimation

is the maximum variance of the discrete-time transfer function estimator over a frequency range [!B;!B]. It is commonly believed that the cost increases as the model complexity increases. The objective of this paper is to quantify this dependence. In particular, we establish several properties of the cost

, with one third fewer terms re-quired on average. That well-known approach is generalized here to a radix-4 CSD system that turns out to save 36 % relative to conventional CSD in the FIR-filter application but at a per-filter overhead cost of six small-integer scaling operations that represent common

Abstract- An approach for broadband modem FIR filter design optimization is presented. It addresses the minimization of the number of adder-subtractors used in the hardware implementation of a FIR filter (Multiple Constant Multiplication problem). The method is based on identification

Abstract-Multiple constant multiplication scheme is the most effective common sub expression sharing technique which is used for implementing the transposed FIR filters. Ripple carry operation allows adder tree to minimize hardware cost, unfortunately it detriment timing and gives low speed
