    The role of the electrostatic generator as a particle accelerator in the field of nuclear physics is that of a precision instrument. It is capable of producing scientific data with high voltage accuracy and is, within its limited voltage range, an almost ideal tool for this type of research. The design of the generator, its advantages, limitations, and the auxiliary equipment necessary to make it ... View full abstract»

    The general approach to the problems of miniaturization is outlined with special emphasis on problems caused by the high operating temperatures. In addition to the general techniques, both conventional and printed circuit, three models of miniature wide-band, high-gain radar-type intermediate-frequency amplifiers (having similar characteristics) are described. A discussion of production methods an... View full abstract»

    This paper covers a theoretical survey of the factors involved in establishing the effect on a desired signal of several interfering signals, including noise. It makes some suggestions toward the solution of the problems involved, and discusses the related problem of defining service area for broadcasting in the very-high and ultra-high frequencies.

  • The p-Germanium Transistor

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1808 KB)

    The transistor effect in p-type germanium is discussed and some properties are given for p-germanium transistors made in the laboratory. These exhibit higher cutoff frequency and somewhat lower current multiplication than their n-germanium counterparts. Under certain conditions a negative resistance "snap" effect is observed which is apparently peculiar to p-type germanium. Both types of transisto... View full abstract»

    The problem of determining the distribution of current in and the impedance of a cylindrical antenna asymmetrically driven by a discontinuity in scalar potential is formulated. An integral equation is derived and solved by the method of successive approximations to obtain general expressions for the current and the impedance. A simple approximate expression for the impedance of the asymmetrically ... View full abstract»

    The first part of this paper is a resumé of correlation analysis. An interpretation of the correlation function of a continuous random process is given in terms of the sum of the products obtained by representing the process as a discrete time series. An electronic correlator capable of performing the necessary mathematical operations to obtain correlation functions is described. The theory o... View full abstract»

  • The Traveling-Wave Cathode-Ray Tube

    We have constructed cathode-ray tubes utilizing traveling waves, whose deflection sensitivity can be made independent of frequency by equalizing the phase velocity of the wave and the electron velocity. According to the theoretical analysis, the sensitivity of this tube is increased to 10-1mm/v at 30 kMc without any difficulty. The results of the theoretical analysis are proved experime...

    Because of the skin effect, the surface condition of conductors becomes very important in determining attenuation at microwave frequencies. This has been investigated by measuring small wire samples at a frequency of about 9,000 megacycles. A sample of the wire to be measured is inserted in a metal tube to form the center conductor of an open-ended coaxial line. The ratio of the peak frequency to ... View full abstract»

  • Cascade-Connected Attenuators

    Publication Year: 1950, Page(s): 1190

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (132 KB)

    Two or more calibrated attenuators are often connected in series (cascade) in order to obtain a desired reduction in power level. The total attenuation of the combination is usually obtained by adding the attenuation of each unit. In general, this will not give the correct result because of reflections due to mismatch at the attenuator junctions. It is shown how the correct value of attenuation ca... View full abstract»

  • The Design of Frequency-Compensating Matching Sections

    Frequency-compensating networks have been employed to improve the impedance bandwidth of antennas and other radio-frequency components. The general problem considered here is that of transforming an impedance which changes with frequency to a specified resistance which is, as nearly as possible, constant with frequency. A simple procedure for solving the general problem is established, and formula... View full abstract»

  • Signal-to-Noise Improvement through Integration in a Storage Tube

    Random noise places a fundamental physical limitation on the precision with which a signal may be observed or measured. In the case where signal energy arrives piecemeal in a repetitive manner, this energy may be integrated over a period of time to provide an increase in signal-to-noise ratio, thereby reducing this limitation. Several techniques have been suggested for performing this integration ... View full abstract»

  • Distortion-Band-Pass Considerations in Angular Modulation

    The distortion introduced into an angular modulated signal transmitted through a network or medium is analyzed using the sideband approach. An exact open-form solution of the output signal is derived; however, the usefulness of this equation is limited by the ability to perform the indicated integrations. It is shown that exact solutions may readily be found for transfer functions which are linear... View full abstract»

    The pulse response of exponential transmission lines is analyzed and it is suggested that such lines may be used advantageously as pulse transformers with short, rapidly rising pulses, particularly where large amounts of power are involved. A subsequent paper will discuss design problems and experimental results. View full abstract»

  • Measurement of the Electrical Characteristics of Quartz Crystal Units by Use of a Bridged-Tee Network

    A bridged-tee null network has been used to measure the equivalent resistance and the equivalent reactance of a quartz crystal plate. This measuring circuit has the advantages that shielding is relatively simple (both the source and the detector have a common grounded terminal) and that corrections for all stray capacitances that affect the measurements may be included in the calibrations of the c...
