    A voting technique is used to diagnose fault conditions down to component level in a feedback control system using only the input-output cross-correlation function measured at suitable time delays. These time delays are chosen using a new formula based on Bayes's theorem, which ranks the time delays in order of usefulness in fault diagnosis; it can be readily applied at the design stage, thus assi...

  • Signal/noise ratio of travelling-wave dipole

    Publication Year: 1973, Page(s):534 - 536
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (261 KB)

    A travelling-wave dipole consisting of conventional arms with a resistance R placed at¿/4 from each end is analysed to enable a comparison of its signal/noise ratio with that of a standing-wave dipole of equal length to be made. Numerical results as a function of sky temperature are given when the dipole length is 3¿/2. View full abstract»

  • Matrices for dual representation of four-terminal non-uniform transmission lines

    Publication Year: 1973, Page(s):537 - 544

    The matrix characterization of general fourterminal non-uniform transmission lines is derived by current and voltage gradient considerations and appropriate application of boundary conditions. The parameters allow ready simplification to any particular component cascade for any class of non-uniformities with solutions expressible in separable variables. By invoking the Principle of Duality, the co... View full abstract»

  • The effect of amplifier gain-bandwidth product on the performance of active filters

    Publication Year: 1973, Page(s):547 - 552

    An expression for the sensitivity of a general second-order RC-active filter section to the finite gain-bandwidth product of the active elements (assumed to be first-order operational amplifiers) is derived and used to classify a number of well known active filter configurations according to the values of certain parameters of the general section. The circuits with a good high-frequency performanc... View full abstract»

  • Hybrid computer simulation applied to digital communication systems

    Publication Year: 1973, Page(s):553 - 561
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1208 KB)

    A large hybrid computer has been used to simulate modern communication systems, particularly those using digital radio techniques. This paper describes the basic thinking behind these models, outlines some of the techniques used and takes, as an example, a digital f.s.k. radio system. The unique results obtained, especially with regard to co-channel interference show the versatility and power of t... View full abstract»

    The relationships between bit error probability and transmitter power are presented on a common basis for various binary and m-ary modulation schemes operating with the same system data rate. it is assumed that the channel is disturbed by additive white gaussian noise of fixed power spectral density and that optimal matched filter reception is used. the results presented allow a comparison of the ...
