  • Flip-Flop Sensor Controlled by Slow-Rise Control Pulse 

    Kollar, M. (Společnost pro radioelektronické inženýrství, 2001-09)
    In this paper we deal with dynamic properties of the flip-flop sensor. Special attention will be paid to the condition of control by slow-rise segment of the control pulse and the derivation of the equivalent voltage. The ...

  • Pseudo-Chaotic Sequences Generated Using Integer-Number Iterations 

    Sebesta, V.; Kolouch, J. (Společnost pro radioelektronické inženýrství, 2001-09)
    A proposed system generates a pseudo-chaotic sequence using integer-number look-up-table (LUT). The current output of LUT is used as LUT input address in the next step. The generated sequence approximates or simulates a ...

  • Filtering of the Color Images Distorted by Impulse Noise 

    Stupak, C. (Společnost pro radioelektronické inženýrství, 2001-09)
    The paper deals with color image filtering distorted by impulse noise. The component, transformation, and vector filtering are analyzed. The filters are evaluated besides the classical criteria (mean absolute error and ...

  • Acceleration of Area Shift Calculation 

    Jurik, R. (Společnost pro radioelektronické inženýrství, 2001-09)
    The goal of the area shift measurement is to find the coordinates (location) of the searched pattern of one two-dimensional sequence in the second two-dimensional sequence. It is supposed that searched pattern is included ...

  • Volterra Filtering for ADC Error Correction 

    Mikulik, P.; Saliga, J. (Společnost pro radioelektronické inženýrství, 2001-09)
    Dynamic non-linearity of analog-to-digital converters (ADC) contributes significantly to the distortion of digitized signals. This paper introduces a new effective method for compensation such a distortion based on application ...

  • Synthesis of Optimized Piecewise-Linear Systems Using Similarity Transformation, Part I: Basic Principles 

    Kolka, Zdeněk (Společnost pro radioelektronické inženýrství, 2001-09)
    Practical realization of nonlinear dynamic systems based on their state models raises an issue of finding such a form with low sensitivity to changes of network parameters. Present paper deals with a method for sensitivity ...

  • Nodal Analysis of Circuits Containing Current Conveyors 

    Rybin, A. I.; Dostal, T. (Společnost pro radioelektronické inženýrství, 2001-09)
    A special method of the nodal analysis of the circuits containing several types of the multiport current conveyors is presented in this paper. The method is based on the given regular and homogeneous models of the irregular ...

  • Design and Implementation of Wave Digital Filters 

    Antosova, M.; Davidek, V. (Společnost pro radioelektronické inženýrství, 2001-09)
    One of possibilities of the Wave Digital Filters (WDF) design is using the classical LC-filters theory. The aim of this paper is to demonstrate the design of WDF from the LC filter and the implementation of WDF on the ...

  • Radar Target Classification Using Neural Network and Median Filter 

    Matousek, Z.; Kurty, J. (Společnost pro radioelektronické inženýrství, 2001-09)
    The paper deals with Radar Target Classification based on the use of a neural network. A radar signal was acquired from the output of a J frequency band noncoherent radar. We applied the three layer feed forward neural ...

  • Synthesis of Optimized Piecewise-Linear Systems Using Similarity Transformation, Part II: Second-Order Systems 

    Pospisil, J.; Kolka, Zdeněk; Horska, J. (Společnost pro radioelektronické inženýrství, 2001-09)
    State models of dynamical systems can be used as prototypes in practical realization of electronic chaotic oscillators. Experimental verification shows that namely eigenvalue sensitivities of these prototypes are very ...

  • The Color Splitting System for TV Cameras - XYZ Prism 

    Kaiser, J.; Kostal, E. (Společnost pro radioelektronické inženýrství, 2001-09)
    One of the dominant aspects, which prejudices the quality of color image reproduction, is the first operation in TV chain - scanning. Up to this day, the color splitting system, working in RGB colorimetric system, is still ...
