  • A Neural LUM Smoother 

    Lukac, R.; Marchevsky, S. (Společnost pro radioelektronické inženýrství, 2000-09)
    In this paper a design of neural LUM smoother is presented. The LUM smoother distinguishes by a number of smoothing characteristics done by the filter parameter. However, the tuning parameter for smoothing is fixed for ...
  • Modeling of Modern Active Devices for Simulations of Analog Circuits in PSpice 

    Dostal, T. (Společnost pro radioelektronické inženýrství, 2000-09)
    Suitable models of the modern active components and functional blocks, namely new types of current conveyors, operational and transimpedance amplifiers, in several appropriate levels, using analog behavioral modeling are ...
  • Order-Statistic Filters in Dynamic Image Sequences 

    Lukac, R.; Stupak, C.; Marchevsky, S.; Macekova, L. (Společnost pro radioelektronické inženýrství, 2000-09)
    This paper is concerned with filtering methods in dynamic image sequences corrupted by impulsive noise. Spatial filters based on order statistics are well known. However, image sequences can be considered as spatiotemporal ...
  • Comparison of Sensitivity Properties of Selected Models of Dynamical Systems 

    Horska, J. (Společnost pro radioelektronické inženýrství, 2000-09)
    In this paper the piecewise-linear (PWL) autonomous dynamical systems are described. The sensitivity properties for all models are calculated (analytically and numerically). We will start with circuit model of 2nd-order ...
  • Novel Approach to Indoor Propagation Modeling 

    Pechač, Pavel; Klepal, M.; Novotny, K. (Společnost pro radioelektronické inženýrství, 2000-09)
    An indoor propagation prediction for personal communication systems is demanded for modern wireless services. There are two main general approaches for indoor propagation modeling: empirical and deterministic. Both of them ...
  • New Reference State Model of the Third-Order PWL Dynamical Systems 

    Pospisil, J.; Brzobohaty, J.; Kolka, Zdeněk; Horska, J. (Společnost pro radioelektronické inženýrství, 2000-09)
    Starting from the first elementary canonical state model, the new simple state model of the third-order dynamical systems that belong to Class C is derived. A typical property of this new model is a very simple form of its ...
