Decimator filter based on B-splines
Ferrer Arnau, Luis Jorge; Roset Juan, Francesc Xavier; Mon González, Juan; Parisi Baradad, Vicenç (2013)
Conference report
Open AccessThe cascaded integrator-comb (CIC) filters are widely used as decimators in many applications, such as in delta sigma AD converters to decimate the sampled signal on its output. One problem with these filters is that by ... -
Divertimento con wavelets

Conference report
Open AccessEn este trabajo se presenta una pequeña introducción a las wavelets. Estas se interpretan com otra forma de mirar la inormación, formada por diferentes niveles o capas. En concreto se pone el ejemplo de una wavelet basada ... -
Effects of nonidealities in switching frequency modulation techniques:application to Coupled Interleaved Multicellular Parallel converters
Mon González, Juan; González Díez, David; Ferrer Arnau, Luis Jorge; Labrousse, Denis; Costa, François (2013)
Conference report
Open AccessThis paper explores the application of the Variable Delay Frequency Modulation (VDFM) to an Interleaved Multicellular Parallel converter. VDFM is a modulation technique specially intended to reduce conducted EMI generated ... -
Efficient cubic spline interpolation implemented with FIR filters
Ferrer Arnau, Luis Jorge; Reig Bolano, Ramon; Marti Puig, Pere; Manjabacas, A.; Parisi Baradad, Vicenç (2012-06-26)
Article
Open AccessClassical Cubic spline interpolation needs to solve a set of equations of high dimension. In this work we show how to compute the interpolant using a FIR digital filter, with a reduced number of operations per interpolated ... -

Efficient representation of contours using splines implemented with FIR filters
Ferrer Arnau, Luis Jorge; Parisi Baradad, Vicenç; Reig Bolano, Ramon; Marti Puig, Pere; Manjabacas, A. (2011)
Conference report
Restricted access - publisher's policyThe interpolation of contour pixels, with splines, of an order greater than or equal to two, usually causes oscillations that do not fit the original shape. To overcome this we propose using a least squares filter before ... -
Feature selection for analyzing and retrieving fish otoliths using elliptic Fourier descriptors of shapes
Reig Bolano, Ramon; Marti Puig, Pere; Gallego, Esteve; Masferrer, Gerard; Lombarte, A.; Ferrer Arnau, Luis Jorge; Parisi Baradad, Vicenç (2011)
Conference report
Restricted access - publisher's policyThis paper analyzes the characteristics of an experimental otolith retrieval system based on image contours described with Elliptical Fourier Descriptors (EFD). Otoliths are found in the inner ear of fish. Their shape ...
