Filed: 1988-01-15
Granted: 1991-02-26
Abstract: "Calculation of Filter Factors for Digital Filter"             ABSTRACT OF THE DISCLOSURE An apparatus for calculating a filter factor for a digital filter which can be made with a simple construction and in which the time period for calculation can be shortened as compared with conventional techniques.  The apparatus comprises an inputting circuit for inputting a desirable frequency property, a division circuit for dividing the inputted frequency property into a plurality of frequency bands, and a calculating circuit for obtaining filter factors for realizing a frequency property of each of the divided frequency bands.  The inputting circuit inputs the frequency property with a frequency resolution corresponding to the number of the filter factors.  The division circuit performs a correction for a division so that the frequency property becomes zero from a frequency over the high cut-off frequency of a band-pass filter toward the Nyquist frequency of the frequency band corresponding to the transversal filter, the Nyquist frequency being 1/2 of the sampling frequency.  The calculating circuit has a transformation unit for performing a Hilbert transformation or a linear phase transformation with respect to the respective frequency properties divided by said division means.

Granted: 1993-08-03
Abstract: Abstract Video-Signal Coder with DPCM and Adaptive Prediction For a video-signal-coding facility using adaptive DPCM in which switching is effected block by block between different predictors, a circuit configuration is given for the case where switching is to be effected between a two-dimensional intraframe predictor and a pure interframe predictor (Fig. 1). Uniform processor elements (PE1, PE0) cooperate with predictor loops (Pr1, Pr2, 10, 11), and means are provided which ensure that the appropriate reconstructed sample values (x0', x1') are used after switching has been effected. The values of the intraframe prediction are calculated in two separate loops, as is known per se. In  a  preferred embodiment (Fig. 3), the decision on the best suited coder is de-layed by one block, whereby the maximum processing speed is substantially increased. Means (PE2, 12, 13, S3, S4, S4') are provided which ensure that even in case of such a delayed decision, the correct recon-structed sample values (x0', x1', x2') are used after a switchover.

Abstract: The present invention relates to intermediate melting sucrose fatty acid ester compositions that are capable of rapid crystallization from a melted state. The compositions comprise 60% to 97% by weight intermediate melting sucrose fatty acid esters and 3% to 40% hardstock triglycerides or hardstock polyol fatty acid esters. Preferably the average fatty acid chain length of the hardstock material fatty acids is not less than the average fatty acid chain length of the intermediate melting sucrose ester fatty acids. The sucrose fatty acid esters are characterized by their rheology, liquid/ solid stability, iodine value, and solids at body temperature. Rapid crystallization of the esters is useful in preventing anal leakage, and it could also translate into a reduction of post-hardening in shortenings and margarines, and into improved high temperature stability and temperature cycling stability as may be encountered during distribution of these products to the end user.
