Novel approach in the design of 2−D extremely narrow bandstop FIR filters is presented. The completely analytical design method is based on the 1−D optimal bandstop FIR filters. The 1−D FIR optimal bandstop filters are based on Zolotarev polynomial. Closed form formulas for the design of the filters are presented. One example demonstrates the design procedure. One application of the 2−D narrow ...

This paper proposes the implementation of digit-serial Canonical Signed-Digit (CSD) coefficient FIR filters which can be used as format conversion filters in place of the ones employed for the MPEG2 TM5 (test model 5). A canonical digit representation of signed numbers is used to reduce the complexities in multiply operations. Practical design guidelines of digit-serial CSD FIR filter are provi...

This paper presents a novel approach of designing linear phase FIR low pass filter using cuckoo Search Algorithm (CSA). FIR filter design is a multi-modal optimization problem. The conventional optimization techniques are not efficient for digital filter design. An iterative method is introduced to find the best solution of FIR filter design problem.Flat passband and high stopband attenuation a...

In this paper we propose a zero forcing (ZF) timevarying (TV) finite impulse response (FIR) equalizer for doublyselective (timeand frequency-selective) channels. We use the basis expansion model (BEM) to approximate the doubly-selective channel and to design the TV FIR equalizer. This allows us to turn a large TV problem into an equivalent small time-invariant (TIV) problem, containing only the...

In this paper, finite impulse response (FIR) control is addressed for H∞ output feedback stabilization of linear systems. The problem we deal with is the construction of an output feedback controller with a certain finite impulse response structure such that the resulting closed-loop system is asymptotically stable and a prescribed H∞ norm bound constraint is guaranteed. Some solvability condit...

H. S. Kwok Hong Kong University of Science and Technology Center for Display Research and Department of Electronic and Electrical Engineering Clear Water Bay, Kowloon Hong Kong Abstract. We present an optical finite impulse response (FIR) filter design method. Based on crystal birefringence, an optical FIR filter can be designed to produce arbitrary spectrum output. A mathematic model of the op...

BACKGROUND The molecular mechanisms that govern cambial activity in angiosperms are well established, but little is known about these molecular mechanisms in gymnosperms. Chinese fir (Cunninghamia lanceolata (Lamb.) Hook), a diploid (2n  = 2x  = 22) gymnosperm, is one of the most important industrial and commercial timber species in China. Here, we performed transcriptome sequencing to identify...

In this paper, we review some basic definitions and properties of FIR filters. We also discusses different types of realizations of digital FIR filters and their uses in some typical applications. We then present some basic building blocks for SC filters. Of particular interest are static and dynamic memory SC circuits, based on SC integrators. These building blocks are the basis for many types...

Mammalian cells chronically exposed to ionizing radiation (IR) induce stress response with a tolerance to the subsequent cytotoxicity of IR. Although p53 is well documented in IR response, the signaling network causing p53 activation in chronic IR remains to be identified. Using breast carcinoma MCF+FIR cells that showed a transient radioresistance after exposure chronically to fractionated IR ...

Abslract-In a companion paper, we studied the system-theoretic properties of discrete time transfer matrices in the context of inversion, and classified them according to the types of inverses they had. In particular, we outlined the role of CAusul FIR matrices with AntiCAusal FIR inverses (abbreviated cafacaj) in the characterization of FIR perfect reconstruction (PR) filter banks. Essentially...
