The paper briefly describes the basics of frequency filter design method using synthetic immittance elements with current conveyors. An introduction of the paper explains the advantages and also disadvantages of using this method. Other chapters briefly introduce a design process of simple second order lowpass and high-pass filter. A theory of current conveyors is discussed too, because they ar...

In this paper, a resistorless realization of high order voltage mode wave active filter based on differential voltage current controlled conveyor transconductance amplifier (DVCCCTA) is presented. The wave method is used for simulating reflected and incident wave for basic building block i.e. series inductor and configuring it for other passive element realization by making appropriate connecti...

We consider a class of robust, rank-based signal processing filters, particularly with regard to its usefulness in the power electronics field. This class of nonlinear filters is characterized by the inclusion of a sorting element in the signal path. The sorting operation allows these filters to suppress impulsive noise while preserving edges and monotonic sections of signals. This introductory...

Digital Image and Volume Correlation (DIC DVC) are non-contact measurement techniques that used during mechanical testing for quantitative mapping of full-field displacements. The relatively high noise floor DIC DVC, which is exasperated when differentiated to obtain strain fields, often requires some form filtering. Techniques such as median filters or least-squares fitting perform poorly over...

Comparisons of six heating source localisation measurement models are conducted where temperature or ultrasonic time of flight readings provide the measurement update to the extended Kalman filter for estimating the location of a high heat flux spot source on a flat plate. For a particular measurement model, one of two processes are used: 1) directly using the measurements as the measurement ve...

Superconvergence of discontinuous Galerkin methods is an area of increasing interest due to the ease with which higher order information can be extracted from the approximation. Cockburn, Luskin, Shu, and Süli showed that by applying a B-spline filter to the approximation at the final time, the order of accuracy can be improved from O(hk+1) to O(h2k+1) in the L2-norm for linear hyperbolic equat...

Let us say that a class of upward closed sets (upsets) distributive lattices is finitary filter if it under homomorphic preimages, intersections, and directed unions. We show the only classes upsets are formed by what we call n-filters. These related to finite Boolean lattice with n atoms in same way filters two-element lattice: n-filters precisely intersections prime pre-images n-filter non-ze...
