    If the uncertainty principle of quantum mechanics is applied to the process of signal measurement, two theorems relating to amplifier noise performance can be deduced. First, it can be shown that it is impossible to construct a linear noiseless amplifier. Second, if the amplifier is characterized as having additive white Gaussian noise, it can be shown that the minimum possible noise temperature o... View full abstract»

  • Negative L and C in Solid-State Masers

    The analysis of solid-state cavity masers is extended to include the reactive component of the paramagnetic resonance. This reactance is inverted (in opposition to Foster's reactance theorem). A two-cavity network makes use of this negative frequency dependence of reactance to obtain a broad-band flat-topped amplifier response. In verification of this theory a ruby maser has been built which has a... View full abstract»

  • Introduction to the Theory of VLF Propagation

    This paper is a self-contained exposition of the conventional theory of propagation of VLF radio waves. The model is a spherical earth surrounded by a concentric ionosphere. Although the model is highly idealized, the theory is still quite involved. The complexities arise from the long wavelengths inherent in such problems. In Section I the elementary geometrical or hop theory for VLF is considere... View full abstract»

  • Composite Characteristics of Negative Resistance Devices and Their Application in Digital Circults

    Publication Year: 1962, Page(s):1648 - 1656

    When a number of negative resistance elements are interconnected, a multistable voltage-current characteristic will be generated. The form of this composite characteristic will depend on the mode of interconnection and on the characteristics of the individual elements. 2n stable states can be generated using n negative resistance elements when the individual characteristics of the elements obey ce...

  • Phase-Stable Oscillators for Space Communications, including the Relationship between the Phase Noise, the Spectrum, the Short-Term Stability, and the Q of the Oscillator

    Highly phase-stable, crystal-controlled oscillators are playing an increasingly important role in extending the range of deep-space communications. For example, during a recent radar experiment with the planet Venus, then at a range of 35-million miles, real-time detection was accomplished with a receiver bandwidth of 5 cps and a search frequency of 2388 Mc. Spectral measurements of the Venus-refl... View full abstract»

  • Harmonic Generation, Rectification, and Lifetime Evaluation with the Step Recovery Diode

    This paper deals with a p-n junction device which will be called a "Step Recovery Diode" because its conductivity variation during reverse recovery approximates a step function. The transition from reverse storage conduction to cutoff for this diode can occur in about a nanosecond, and it can produce associated discontinuities up to about an ampere and/or a hundred volts. This step recovery action... View full abstract»

  • Frequency Sounding Techniques for HF Communications over Auroral Zone Paths

    This paper presents evidence that systematic oblique incidence channel sampling transmissions are valuable for improving the reliability of air-ground HF communications when propagation conditions are marginal. This evidence results from air-ground radio communications trials supplemented by frequency sounding transmissions over flight paths of up to 1260 nautical miles into auroral zone latitudes...
