Abstract
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.
