    Integrated-circuit binary shift registers are used to realize the matched-filter to randomly coded radar signals. The system exploits the favourable range side-lobe properties of randomly changing binary codes to achieve pulse compression ratios greater than those obtainable with fixed coding schemes. The output noise distribution, signal/noise ratio, range resolution characteristics, range side-l... View full abstract»

    Alpha-numerics are used to identify broadband radar targets on a p.p.i. display for air traffic controllers. A technique for writing the broadband data is described which reduces the time required to a constant time independent of radar display range. This constant time can be chosen so that adequate time is allotted for the writing of radar target associated alpha-numeric data. For alpha-numerics... View full abstract»

  • Synthesis of the ungrounded inductor with grounded amplifier realizations

    Publication Year: 1968, Page(s):53 - 59
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (650 KB)

    The ungrounded inductor is approximated closely by the transmission matrix (1,Ls; g, 1), where L = CR2, by making g sufficiently small. A representation of this matrix is obtained by a form of synthesis procedure and realized in active-RC form, with L derived by inversion of a capacitor C, using a minimal number of grounded operational amplifiers of only one type. The theory has been confirmed exp... View full abstract»

  • Design of resistively mismatched single amplifier stages

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (477 KB)

    Resistively mismatched, reactively tuned single amplifier stages can be designed for a given measure of stability or performance factor, n, by the analytical solution of appropriate equations. The present paper provides a computer solution in the form of graphs for values of performance factor ranging between 1 and 10 and a closely accurate analytical solution for n ¿ 10. Using these results, des... View full abstract»
