  • Preliminary Results of Ocular Artefacts Identification in EEC Series by Neural Network 

    Kofronova, M. (Společnost pro radioelektronické inženýrství, 1996-06)
    The human electroencephalogram (EEG), is record of the electrical activity of the brain and contains useful diagnostic information on a variety of neurological disorders. Normal EEG signal are usually registered from ...
  • The Current Distribution and Characteristic Impedance of Multiwire Hexaedric Antenna 

    Novacek, Z. (Společnost pro radioelektronické inženýrství, 1996-06)
    Both the current distribution and characteristic impedance variations along a hexaedric antenna are analysed in this paper. The presented arrangement by auxiliary wires may ensure equal currents in all antenna wires. The ...
  • Broadband Utilization of Eigenvalue Techniques 

    Nebus, F.; Kus, Z. (Společnost pro radioelektronické inženýrství, 1996-06)
    A large number of signal processing problems are concerned with estimating unknown parameters from sensor array measurement. This paper presents simple algorithm for estimating spatio-temporal spectrum of signals received ...
  • Design of IIR Filters by Impulse Response Optimisation 

    Novotny, M.; Jan, J. (Společnost pro radioelektronické inženýrství, 1996-06)
    The contribution describes a program system to design digital IIR filters by optimisation of impulse response. Besides briefly presenting the already published method, it emphasizes the necessity to regularize the problem ...
  • Optimizing Transmission Line Matching Circuits 

    Novak, S. (Společnost pro radioelektronické inženýrství, 1996-06)
    When designing transmission line matching circuits, there exist often overlooked, additional, not much used, degree of choice in the selection of the transmission line impedance. In this work are presented results of CAD ...
  • Microstrip Phased Array Antennas Printed on Inclined Planes 

    Augustin, D.; Staraj, R.; Cambiaggio, E.; Papiernik, A. (Společnost pro radioelektronické inženýrství, 1996-06)
    This paper presents an analysis of the electromagnetic field radiated by micro-strip patch antennas printed on inclined surfaces. The theoretical approach allows to apply spatial rotations to each source. The computer ...
  • Floating RC Networks Using Current Conveyors 

    Vrba, K.; Cajka, J.; Zeman, V. (Společnost pro radioelektronické inženýrství, 1996-06)
    The paper deals with the design of floating one- and/or two-port high-order networks. The current conveyor CCII+ seems to be a suitable active building block for this purpose. Some examples of the above mentioned networks ...
