  • A Simple Method of Measuring the Noise Figure of the NMR Spectometer 

    Kasal, M.; Husek, V.; Halamek, J. (Společnost pro radioelektronické inženýrství, 1993-07)
    Sensitivity is one of the fundamental parameters of the Nuclear Magnetic Resonance experiment. It depends particularly on the coil and impedance matching of the resonance circuit of the probe to the input amplifier. However, ...
  • Switched Capacitor Equivalent of Frequency Dependent Negative Resistor 

    Mikula, J.; Dostal, T. (Společnost pro radioelektronické inženýrství, 1993-07)
    A new circuit of frequency dependent negative resistor (FDNR), derived using an almost linear s-z transformation in a four phase switched capacitor (SC) network is presented.
  • Multiple-Dwell Serial-Search Code Acquisition of Spread-Spectrum Receiver - Mean Acquisition Time at Fixed False-Alarm Penalty 

    Simsa, J.; Triska, I. (Společnost pro radioelektronické inženýrství, 1993-07)
    The contribution summarizes the results of the mean code acquisition time calculations of multiple - dwell serial search detector with fixed false-alarm penalty. The repeated calculations enable to choose optimum values ...
  • A Novel Approach to the Speech and Channel Coding System 

    Cizmar, A. (Společnost pro radioelektronické inženýrství, 1993-07)
    In this paper a novel approach to the speech-and-channel coding system is proposed. The main idea of this approach is splitting an input speech signal into its integer and fractional parts and their different coding to ...
  • Full Custom Design of a 8-bit Subranging Flash A/D Convertor 

    Vanneuville, J.; Gevaert, D.; Sevenhans, J. (Společnost pro radioelektronické inženýrství, 1993-07)
    This paper describes the design of a Nonius Flash Analog to Digital Convertor for video-applications. The conversion is split up in two stages: the MSB and the LSB conversion stage. In the LSB conversion stage, the ...
