This paper first describes an algorithm that finds the approximate finite impulse response (FIR) inverse of an FIR filter by minimizing the inversion (or reconstruction) error constrained to zero-bias. The generalization of the inverse filtering problem in the two channel case is the design of perfect reconstruction filter banks that use critical sampling. These considerations lead to the deriv...

With the continuing trends to reduce the chip size and integrates multichip solution into a single chip solution it is important to limit the silicon area required to implement parallel FIR digital filter in VLSI implementation. The Need for high performance and low power digital signal processing is getting increased. Finite Impulse Response (FIR) filters are one of the most widely used fundam...

The accumulation of advanced glycation end products (AGEs) in diabetic patients induces vascular endothelial injury. Promyelocytic leukemia zinc finger protein (PLZF) is a transcription factor that can be activated by low-temperature far-infrared (FIR) irradiation to exert beneficial effects on the vascular endothelium. In the present study, we investigated the influence of FIR-induced PLZF act...

Advances in nanoelectronic fabrication have enabled integrated circuits to operate at a high frequency. The finite impulse response (FIR) filter needs only to meet real-time demand. Accordingly, increasing the FIR architecture’s folding number can compensate the high-frequency operation and reduce the hardware complexity, while continuing to allow applications to operate in real time. In this w...

| W e present a novel method{ lter decomposition approach, for multichannel blind de-convolution of non-minimum phase systems. In 20] we has developed an eecient natural gradient algorithm for causal FIR lters. In this paper we further study the natural gradient method for non-causal lters. We decompose the doubly nite l-ters into a product of two lters, a noncausal FIR lter and a causal FIR lt...

effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with borax. nanosilver and borax were applied in pressure vessel using rueping method. the size range of silver nanoparticles was 20-80 nm. specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...

this study was aimed to investigate the bending moment and stress (inner and outer corners) in lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (mdf). for this purpose, l-shaped joints made of beech and fir, particleboard and mdf by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). bending moment and stress carrying capacity of...

Seedlings of ponderosa pine, Douglas-fir, white fir, Engelmann spruce, and subalpine fir were exposed continuously to charcoal-filtered (CF) air or one of three levels of a simulated ambient exposure typical of SO, pollution near smelters in the western United States. Seedlings were exposed during winter-spring experiments for 60 days to hourly means of 17, 38, and 54 ppb in 1988 and 35, 57, an...
