Z-transformstabilityroot-mapThis chapter introduces 2-D difference equations and the Z transform including recursive filter stability theorems. It is a generalization of the 1-D Z-transform used in the analysis and synthesis of 1-D linear constant coefficient difference equation-based systems. In ...
Only a few works in the literature have dealt with the hardware implementation of the VVC transforms. Some of which have targeted the optimization of the transforms using the approximation approach. This study proposes a unified two-dimensional architecture that provides exact and approximate DST-VII ...
We obtain a Fourier transform scaling relation to find analytically, numerically, or experimentally the spectrum of an arbitrary scaled two-dimensional Dirac delta curve from the spectrum of the nonscaled curve. An amplitude factor is derived and given explicitly in terms of the scaling factors and...

Let be the two-dimensional Laplace transform, let v and u be weights on (0,∞) 2 , and let 1<p≤q<∞. The aim of the paper is to establish necessary conditions for the boundedness of between weighted Lebesgue spaces, L p ((0,∞) 2 ,v(x 1 ,x 2 )dx 1 dx 2 )→L q ((...

When the source size (i.e., the HBT scale parameter R) or the correlation strength (i.e., the intercept parameter λ) of the Bose–Einstein correlation is to be measured, a full three-dimensional source reconstruction can be performed if the available statistics allow it. While in our ana...
A two-dimensional phase unwrapping approach based on two-dimensional windowed Fourier transform(WFT) is proposed. 提出了一种基于二维短时傅里叶变换的干涉相位图解缠方法。补充资料:傅里叶级数与傅里叶积分 傅里叶级数与傅里叶积分 Fourier series and integrals 傅里叶级数与傅里叶积分(F ourierse-ries ...
Compared to traditional porous materials, the most appealing advantage of MOFs is that using different metal ions and organic linkers so that MOFs can be finely designed to exhibit one-, two-, and three-dimensional (1D, 2D, and 3D) MOF structures4,26. Here we usedp-benzenedicarboxylic acid ...
