FIR filter-based transmitter pre-emphasis has been used to counteract inter-symbol interference (ISI) in high-speed backplane data transmission. In this paper, backplane channel characteristics are analyzed in both time and frequency domains. The analysis performed demonstrates that group delay distortion is a major ISI contributor in addition to amplitude attenuation. A Matlab program is then ...

Decimator is an important sampling device used for multi-rate signal processing in wireless communication systems. In this paper optimized decimator has been presented to improve the implementation complexity. The proposed decimator is implemented using Matlab as standard FIR, Half Band FIR and Nyquist FIR by using the multistage design techniques. The performance of different decimator designs...

This paper presents a novel partially reconfigurable FIR filter design that employs dynamic partial reconfiguration. Our scope is to implement a low-power, area-efficient autonomously reconfigurable digital signal processing architecture that is tailored for the realization of arbitrary response FIR filters using Xilinx FPGAs. The implementation of design addresses area efficiency and flexibili...

Dendrochronological analysis was carried out for 13 historic icons from the collection of the Museum of the Folk Building in Sanok, painted on fir and spruce boards. Eleven sequences of the annual growth rings produced from the analysed fir boards were absolutely dated against the fir dendrochronological standard for S Poland, constructed by E. Szychowska-Krąpiec. Most of the analysed objects d...

Several authors have studied the question of when the monoid ring DM of a monoid M over a ring D is a right and/or left fir (free ideal ring), a semifir, or a 2-fir (definitions recalled in §1). It is known that for M nontrivial, a necessary condition for any of these properties to hold is that D be a division ring. Under that assumption, necessary and sufficient conditions on M are known for D...

Reconfigurability, low complexity and low power consumption are the key requirements in a FIR filter. Many works have been done on the reduction of area and power requirements but Reconfigurability is less addressed in the papers. In this paper, a survey has been conducted on the works done in the past on the Reconfigurability of the FIR filters and various algorithms being used for making the ...

Swiss needle cast (SNC) is a fungal disease of Douglas-fir (Pseudotsuga menziesii) that has recently become prevalent in coastal areas of the Pacific Northwest. We used growth measurements and stable isotopes of carbon and oxygen in tree-rings of Douglas-fir and a non-susceptible reference species (western hemlock, Tsuga heterophylla) to evaluate their use as proxies for variation in past SNC i...

Based on fast finite-impulse response (FIR) algorithms (FFAs), this paper proposes new parallel FIR filter structures, which are beneficial to symmetric coefficients in terms of the hardware cost, under the condition that the number of taps is a multiple of 2 or 3. The proposed parallel FIR structures exploit the inherent nature of symmetric coefficients reducing half the number of multipliers ...

Far infrared radiation (FIR) is currently investigated as a potential therapeutic strategy in various diseases though the mechanism is unknown. Presently, we tested if FIR mediates beneficial effects in a cell model of the neurodegenerative disease spinocerebellar ataxia type 3 (SCA3). SCA3 is caused by a mutation leading to an abnormal polyglutamine expansion (PolyQ) in ataxin-3 protein. The c...
