  • Simple Chaotic Oscillator: From Mathematical Model to Practical Experiment 

    Petrzela, J.; Kolka, Zdeněk; Hanus, S. (Společnost pro radioelektronické inženýrství, 2006-04)
    This paper shows the circuitry implementation and practical verification of the autonomous nonlinear oscillator. Since it is described by a single third-order differential equation, its state variables can be considered ...
  • UWB Propagation through Walls 

    Schejbal, V.; Bezousek, P.; Cermak, D.; Nemec, Z.; Fiser, O.; Hajek, M. (Společnost pro radioelektronické inženýrství, 2006-04)
    The propagation of ultra wide band (UWB) signals through walls is analyzed. For this propagation studies, it is necessary to consider not only propagation at a single frequency but in the whole band. The UWB radar output ...
  • X-Band PLL Synthesizer 

    Vagner, P.; Kutin, P. (Společnost pro radioelektronické inženýrství, 2006-04)
    This paper deals with design and realization of a PLL synthesizer for the microwave X−band. The synthesizer is intended for use as a local oscillator in a K−band downconverter. The design goal was to achieve very low phase ...
