Comparing phase detectors in analog Phase-Locked Loops
(2021-01-01)
The Phase-Locked Loops, conceived in the 1930’s by Henri de Bellescize, and used in a large scale on TV sets and integrated services digital telecommunication networks are nowadays increasing their relevance, being present ...
Radial Basis Functions for Phase Unwrapping
(Revista Computación y Sistemas; Vol. 14 No. 2, 2010-12-15)
Abstract. An important step in fringe pattern analysis is the
so called phase unwrapping. Although this task can be
performed easily using path dependent algorithms, most
times, however, these algorithms are not robust ...
Error analysis of phase detector based on Clarke transform and arctangent function in polluted grids
(Elsevier Science Sa, 2015-06)
Abstract Extracting phase information from a three-phase disturbed signal is a recurrent topic in power systems. The phase detector based on the Clarke transform and the arctangent function is a widely used technique to ...
Almost and asymptotically almost periodic solutions of abstract retarded functional difference equations in phase space
(2011)
We establish the existence of bounded, almost periodic solutions and asymptotically almost periodic solutions for functional difference equations with infinite delay on abstract phase space. An application to Volterra ...
Study of phase congruency quantization function properties for image edge detection
(Proceedings of SPIE - The International Society for Optical Engineering, 2022)
Q-generalization of quantum phase-space representations
(Elsevier Science, 2015-04)
We generate a family of phase space, thermal coherent-state's representations, within the framework of Tsallis' Generalized Statistical Mechanics and study their properties. Our protagonists are q-gaussian distributions. ...
Maximally localized Wannier functions for describing a topological phase transition in stanene
(American Physical Society, 2021-01)
Starting from first-principles calculations on pristine stanene and using maximally localized Wannier functions (MLWFs), we analyze the different phases of the system when it is driven to a topological phase transition. ...
Convergent solutions of linear functional difference equations in phase space
(2003)
By using weighted summable dichotomies and Schauder's fixed point theorem, we prove the existence of convergent solutions of linear functional difference equations. We apply our result to Volterra difference equations with ...
