  • The Current State of Mobile Communications in Europe 

    Black, T. (Společnost pro radioelektronické inženýrství, 1994-03)
    The last decade has seen unprecedented developments in land mobile communications in Europe. The introduction of analogue cellular networks in the early 1980 's started a revolution in technologies and services which, even ...
  • Time Domain Analysis of Linear Systems Using Laplace Inversion 

    Biolek, Dalibor (Společnost pro radioelektronické inženýrství, 1994-03)
    An efficient method of time domain analysis of linear systems is proposed. This method is based on the state space approach and on the numerical Laplace inversion. The problems of the sampled-data input signal and steady-state ...
  • Lattice All-Pole Structure of Digital Filters and Its Zero Input Response 

    Smekal, Z. (Společnost pro radioelektronické inženýrství, 1994-03)
    The lattice structures for linear prediction were formulated in speech processing by Makhoul [1]. The LPC coders are often used in the transmission of speech signals. Such systems include a filter in the receiver that ...
  • Functional Stability Theory and Its Application in Complex Systems 

    Nahlik, J.; Hudec, L. (Společnost pro radioelektronické inženýrství, 1994-03)
    In the contribution the basic principles of the Functional Stability Theory are described, some problems discussed in more details, the Criterion of the Theory is shown, possibilities in Synergetics are mentioned and an ...
  • Fluctuations in LC Oscillators 

    Kulesov, V. N.; Lesukov, B.; Kudjak, V.; Ondracek, O. (Společnost pro radioelektronické inženýrství, 1994-03)
    An analysis of the phase and amplitude fluctuations in oscillators with simple resonant circuit is presented. Negative feedback is used to minimize effect of the inherent noise produced by bipolar transistor on fluctuation ...
  • Design of the Decomposed State Model of an One-Dimensional Piecewise-Linear System 

    Kolka, Zdeněk (Společnost pro radioelektronické inženýrství, 1994-03)
    Present paper deals with the problem of automatic design of the implicit state model (in its decomposed parametric form) of any one-dimensional piecewise-linear (PWL) system. This model consists of the internal and the ...
