Projeto de filtros analógicos
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2018-11-22)
This work elaborates a study of the theory, simulation and solution of some cases considering the use of active and passive analog filters, aiming to complement the study in the electronics area of the Electrical Engineering ...
Cascade Structure for Finite Impulse Response Filters and Linear Prediction
(2012-12)
This paper presents a complete analysis of the cascade
structure for adaptive transversal filters based on
adaptive algorithms. The standard structure of the
cascade transversal FIR filter is obtained by replacing
the ...
An application of particle filter for FDI oriented change detection and bounded parameter estimation
(IEEE, 2007)
In their original formulations, state estimation schemes such as Kalman Filter, do not allow the incorporation of prior information on their physical bounds. This results in a certain probability of generating estimates ...
Harmonic, reactive and unbalance compensation by means of CPT framework
(2009-12-01)
This paper presents possible selective current compensation strategies based on the Conservative Power Theory (CPT). This recently proposed theory, introduces the concept of complex power conservation under non-sinusoidal ...
Analysis of a Reconfigurable Bandpass Circular Patch Filter
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper presents an analysis of a reconfigurable patch filter based on a triple-mode circular patch resonator with four radial slots. The analysis has been carried out thanks to the development of a new theoretical ...
Multiple split-ring resonators for tri-band filter with asymmetric response
(Scopus, 2011)
A triple-band filter composed of multiple split ring resonators is presented. This filter is based on a chain of triple split ring resonators that produces three pass-bands. The change in the dimensions of the corresponding ...
Temperature Effects on Suction Measurement Using the Filter Paper Technique
(AMER SOC TESTING MATERIALSW CONSHOHOCKEN, 2012)
This paper presents the results of an experimental study of thermal effects on filter paper calibration curves used to obtain the soil suction. When the temperature is significantly different from ambient values, it is ...
A filtering technique for helping to solve sudoku problems
(Springer Verlag, 2015)
Estimation of an optimal mixed-phase inverse filter
(2000)
Inverse filtering is applied to seismic data to remove the effect of the wavelet and to obtain an estimate of the reflectivity series. In many cases the wavelet is not known, and only an estimate of its autocorrelation ...
On designing linearly tunable high-Q OTA-C filters with low sensitivity
(2004-09-07)
This paper discusses a design approach for a high-Q low-sensitivity OTA-C biquad bandpass section. An optimal relationship is established between transconductances defining the differenceβ - γ in the Q-factor denominator, ...
