  • Autocompensative System for Measurement of the Capacitances 

    Kollar, M.; Spany, V.; Gabas, T. (Společnost pro radioelektronické inženýrství, 2002-06)
    A simple and successful design of an autocompensative system with flip-flop sensor for measurement of capacitances is presented. The analysis of the sensor is based on the state description with the vertical rise segments ...
  • Two Synthesis Methods Based on Cepstral Parameterization 

    Pribil, J.; Madlova, A. (Společnost pro radioelektronické inženýrství, 2002-06)
    The paper deals with two implementations of the speech synthesis based on the cepstral representation of the human vocal tract model. Both the approaches to speech modeling are evaluated in the frequency domain. The paper ...
  • Thermosensitive IC for Relative Temperature Determination 

    Gotra, O.; Kalita, W.; Slosarcik, S.; Pietrikova, A.; Saliga, J. (Společnost pro radioelektronické inženýrství, 2002-06)
    The functioning algorithm and the scheme of the transducer unit applied in thermosensitive IC with relative temperature reading are proposed in this paper. The principal algorithm of functioning is in the formation of ...
  • RC Autonomous Circuits with Chaotic Behavior 

    Bernat, P.; Balaz, I. (Společnost pro radioelektronické inženýrství, 2002-06)
    The paper presents obtained results with applying the "Semi-systematic procedure for producing the chaos from quasi-sinusoidal oscillators". We applied this procedure to RC autonomous circuit and obtained two new autonomous ...
  • High-Order Lowpass Filters Using DVCC Elements 

    Cajka, J.; Dostal, T.; Vrba, K. (Společnost pro radioelektronické inženýrství, 2002-06)
    Special cells using a differential voltage current conveyor are presented. The use of these cells for high-order lowpass filter design is described. The filters can be designed to operate in different modes.
  • Biquad Based on a Generalized Divider Structure 

    Ticha, D.; Martinek, P. (Společnost pro radioelektronické inženýrství, 2002-06)
    The paper deals with the biquad based on a generalized divider structure. This principle can be considered as an effective way of universal filter and equalizers synthesis, which easily realizes any general transfer function. ...
  • Chua's Circuit in Spread Spectrum Communication Systems 

    Galajda, P.; Kocur, D. (Společnost pro radioelektronické inženýrství, 2002-06)
    Communication system via chaotic modulations is demonstrated. It contains the well-known chaotic circuits as its basic elements - Chua's circuits. The proposed system has some standard properties of spread spectrum ...
  • Synthesis of Optimized Piecewise-Linear Systems Using Similarity Transformation. Part III: Higher-Order Systems 

    Pospisil, J.; Kolka, Zdeněk; Hanus, S.; Brzobohaty, J. (Společnost pro radioelektronické inženýrství, 2002-06)
    State models of dynamical systems used as prototypes in their practical realization are optimized from the viewpoint of minimum eigenvalue sensitivities with respect to the change of the individual parameters. In the paper ...
