  • Preventing Inductive Output Impedance of High-Frequency Emitter Follower Stages 

    Nerad, J.; Tozer, R. C. (Společnost pro radioelektronické inženýrství, 1997-04)
    Large output inductance is one of major issues of high-frequency emitter follower design. The most often suggested technique to reduce its value is the decreasing of AC transconductance which offers small output inductance ...
  • Functional Blocks and Biquadratic ARC Filters using Transimpedance Amplifiers 

    Dostal, T.; Prokop, R.; Sarman, R. (Společnost pro radioelektronické inženýrství, 1997-04)
    The aims of the article are design and analysis of modern circuits including high performance functional blocks and biquadratic filters using transimpedance amplifiers. Here are given various types of these circuits, that ...
  • Statistical Identification of Kernels of Discrete Nonlinear Systems 

    Shcherbakov, M. A. (Společnost pro radioelektronické inženýrství, 1997-04)
    A method for identification of discrete nonlinear systems in terms of the Volterra-Wiener series is presented. It is shown that use of a special, composite-frequency input signal as approximation to Gaussian noise provides ...
  • Propagation over Irregular Terrain 

    Schejbal, V. (Společnost pro radioelektronické inženýrství, 1997-04)
    The computer model and computation accuracy for propagation over irregular terrain are presented. Special attention is paid to computation for low altitude propagation and the finite distance between the antenna and the ...
  • Bandpass Signal Processing 

    Halamek, J.; Kasal, M.; Villa, M.; Cofrancesco, P. (Společnost pro radioelektronické inženýrství, 1997-04)
    We present the bandpass signal analysis based on digital receiver and call attention to the aliasing of the complex signal, the digital quadrature detector when sampling is equal to quadruple of the carrier frequency, and ...
