An Optimal Extrapolator for Reducing Phase Delay of Sample Data-hold
نویسندگان
چکیده
The objective of this paper is to minimize the phase delay of the zero-order hold (ZOH) an usual sample-data hold device. In this paper an optimized data holding scheme whose phase delay is significantly less than of the ZOH is presented. The method is based on using optimal extrapolators, which has a better result than extrapolators proposed by Yekutiel (1980) and Belicynski and Kozinski (1984). This method is more general than the other methods. Copyright © 2005 IFAC

Experimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column
An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...
متن کاملDPCM with an adaptive extrapolator for image compression
The method of image compression based on differential pulse-code modulation (DPCM) with an adaptive extrapolator is investigated. This extrapolator automatically adapts to local features of contours (boundaries) in the image. The issue of the negative effect of quantization on the result of optimizing the adaptive extrapolator is investigated. It is experimentally proved that, despite this effe...

In this research, ZrC-ZrB2-SiC nanocomposite powder was synthesized by carbothermal and borocarbotermal reduction methods. Zirconium silicate was first milled for four hours Then eight mixtures of raw materials were prepared. Finally, the samples were pyrolyzed at 800 ° C for two hours and then heat-treated at 1500 ° C for 30 minutes under an argon atmosphere. X-ray diffraction (XRD) and scanni...
متن کاملDual Phase Detector Based Delay Locked Loop for High Speed Applications
In this paper a new architecture for delay locked loops will be presented. One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...
متن کاملDeveloping an Analytical Model and Simulation of The Contraflow Left-Turn Lane at Signalized Intersections
At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...
