  • RC Oscillators with Two Operational Amplifiers with Precision Phase Shift between Two Outputs 

    Horsky, P. (Společnost pro radioelektronické inženýrství, 1996-12)
    In some instruments oscillator with precision 90° phase shift of output signals is needed. In this article a new type of RC oscillators with precision 90° phase shift between two low impedance output signals is described. ...
  • The Transimpedance Amplifier Noise Optimization for the Atmospheric Optical Link Receiver 

    Prokes, A. (Společnost pro radioelektronické inženýrství, 1996-12)
    This paper deals with design of wideband low-noise preamplifier of atmospheric optical link receiver. Sources of noise and the noise models for the PIN photodiode coupled to a transimpedance amplifier are described here. ...
  • Use of Invertible Rapid Transform in Motion Analysis 

    Gamec, J.; Turan, J. (Společnost pro radioelektronické inženýrství, 1996-12)
    The paper presents the results of a study on the use of invertible rapid transform for the motion estimation in a sequence of images. Novel motion estimation algorithms based on the analysis of the matrix of states (or ...
  • Vector Measurement with Scalar Analyser 

    Klusacek, V.; Skvor, Z.; Hoffmann, K. (Společnost pro radioelektronické inženýrství, 1996-12)
    A novel method for vector scattering parameter measurement is presented. The method is based on scalar (SWR) measurement only. Vector data is obtained using a controlled perturbation two-port (CPTP). The method promises ...
