  • An Acoustic Object Recognition System 

    Turan, J. (Společnost pro radioelektronické inženýrství, 1992-10)
    This paper presents the results of a study on use rapid transform to analysis of acoustic echo signals in an acoustic object recognition system. The echo signals are analysed in the time invariant rapid transform domain ...

  • Signal-Flow Graph Network Analysis 

    Dostal, T.; Mikula, J. (Společnost pro radioelektronické inženýrství, 1992-10)
    A novel type of signal-flow graph is presented creating minimum number of nodes for independent voltages only. The graph will be derived by inspection of the network using special transforming T-graphs. The method is useful ...

  • A New Version of the Microstrip to Waveguide Transition 

    Machac, J. (Společnost pro radioelektronické inženýrství, 1992-10)
    A new version of the microstrip-to-waveguide transition is described and analyzed. It is the E-plane transition, where the stripe probe is substituted by a rectangular patch. The structure is very simple, easily adjustable, ...

  • Calibrating the Six-Port Reflectometer Using a Matched Load And Four Unity-Reflection Standards (Part 1) 

    Bilik, V. (Společnost pro radioelektronické inženýrství, 1992-10)
    An alternative six-port calibration procedure is described using an ideal matched load and four unity reflection standards. Not only offset short or open circuits can be used as the reflection standards but also arbitrary ...

  • Multi-Step Numerical Laplace Inversion 

    Biolek, Dalibor (Společnost pro radioelektronické inženýrství, 1992-10)
    An accurate numerical Laplace inversion algorithm is presented. In comparison with original multi-step inversion method, some improvements are made. The concrete Turbo Pascal routines are introduced.
