  • Image Generation by Octree 

    Harakal, M.; Chmurny, J. (Společnost pro radioelektronické inženýrství, 1996-09)
    This paper deals with the generating of three-dimensional (3-D) images by octree and using the application of tesseral theory in image processing.

  • Interference Fading Prediction on the Line-of-Sight Radio Links 

    Hajny, M. (Společnost pro radioelektronické inženýrství, 1996-09)
    The fading on the LOS links is an important factor influencing the reliability of the communication. In this paper predictions models for interference fading are described. Predictions are compared with measured data of ...

  • Unbalanced Czarnul Resistive MOS Circuit in the Symmetrical MOSFET-C Filters 

    Urbas, A.; Galinski, B. (Společnost pro radioelektronické inženýrství, 1996-09)
    The analysis of influence of mismatches of the MOS transistor array on center frequency ω0 and Q-factor of the MOSFET-C filter poles is performed. As a useful parameter characterizing mismatches of transistors, the dispersion ...

  • Analog Hardware Description Language and Its Relations to VHDL 

    Vlcek, K.; Popelek, J. (Společnost pro radioelektronické inženýrství, 1996-09)
    Primary motivations for analogue hardware description language (VHDL-A) is to support the modelling of physical systems. The VHDL-A must therefore allow to model the physical conservation laws, such as the energy conservation ...

  • Prediction of Rain and Water Vapour Attenuation at Frequencies 10-30 GHz 

    Fiser, O. (Společnost pro radioelektronické inženýrství, 1996-09)
    This contribution discusses the attenuation of microwaves in the atmosphere and applies the results to the conditions in the Czech Republic. The simple CCIR method predicting the rain attenuation is described and the ...

  • Restoration of Local Degradations in Audio Signals 

    Brejl, M. (Společnost pro radioelektronické inženýrství, 1996-09)
    The paper presents an algorithm for restoration of local degradations in audio signals. The theoretical foundations and basic suggestions of this algorithm were published in [1]. A complete description of restoration process ...
