    The science of sound, for years one of the most neglected of subjects related to physics, has during the past decade been the subject of much interesting research. A certain amount of impetus has been added to this work by the phenomenal growth of radio broadcasting owing to the necessity of providing studios suitable from an acoustic standpoint. This paper indicates certain facts relative to the ... View full abstract»

  • Accurate Method of Measuring Transmitted Wave Frequencies at 5000 and 20,000 Kilocycles per Second

    Publication Year: 1931, Page(s):35 - 41
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (936 KB)

    The measurement of the frequency of a radio transmitting station offers a convenient means of intercomparison of frequency standards situated in different laboratories. While there have been several articles published dealing with station frequency measurements, these have, for the most part, considered frequencies in the broadcast band or lower. This paper describes a method of measuring station ... View full abstract»

    After outlining the graphical method for the analysis of power tube output as applied to the case of a simple resistive load the method is extended to the case of a plate load presenting a value of resistance that is different for direct current than for alternating current. It is shown that in this case the various load lines cannot be drawn through a common operating point because the effective ... View full abstract»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2128 KB)

    This paper covers all of the systems of power equipment now used or contemplated for supplying power to aircraft radio transmitters. The various types of power equipment are described and the advantages and disadvantages of each type are discussed. The types of power equipment discussed are (1) the wind driven generator, (2) the dynamotor, (3) the main engine driven generator, (4) the auxiliary en... View full abstract»

    Characteristics of various rectifier circuits and factors governing their selection are given. It is pointed out that in general, the double 3-phase circuit is most desirable from the standpoint of transformer and tube capacity requirements for mercury pool type tubes, and the 6-phase single Y for hot cathode mercury vapor tubes or high vacuum tubes, but that other factors may make other circuits ...

  • Note on skip distance effects on super-frequencies

    Publication Year: 1931, Page(s):103 - 105
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (342 KB)

    During the last eighteen months the Naval Research Laboratory has made a very large number of measurements on skip distances in the frequency band between 30,000 and 40,000 kc. Most of the measurements have been taken during the month of January, February, and March, 1929, and the corresponding months of 1930. Since the measurements for the two succeeding years are substantially in agreement we be... View full abstract»

    This paper describes progress in a recently inaugurated program of cooperative research for the study of radio transmission. Oscillographic observations of pulse transmissions made at the Bureau of Standards and Tufts College, in collaboration with workers at the Naval Research Laboratory and the Department of Terrestrial Magnetism, are discussed. Observations on 1410 kc and a number of higher fre... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2016 KB)

    Virtual heights of the Kennelly-Heaviside layer as measured by the radio echo method are reported for 4045 kc and 8650 kc. The report covers daytime observations made each week between January 16 and June 19, 1930. Two evening tests are also described. Curves are given comparing heights with sun spot numbers and magnetic character. Records taken on April 28, 1930, the day of the solar eclipse, are... View full abstract»

  • The Detection of Two Modulated Waves Which Differ Slightly in Carrier Frequency

    The present paper contains an analysis of the detection of two waves modulated with the same, or with different, audio frequencies and differing in carrier frequency by several cycles or more. Both parabolic and straight line detectors are treated and there are derived the expressions for all of the important audio frequencies present in the output of these detectors when such waves are impressed....

    A description is given of tests made to determine whether there is a relation between the interference currents in submarine cables and the atmospheric interference in radio. Racorder and oscillograph photographs show the agreement in a large number of interference signals. Cable and antenna, therefore, are influenced similarly by the same interference processes.

    Summary form only given, as follows. The Bell Telephone Laboratories sent an expedition last summer to Newfoundland for the purpose of measuring the interference picked up on an 8-mile submarine cable in order to determine the amount of interference which might be expected on a transatlantic telephone cable terminated there. The same expedition is engaged in similar measurements this year in Irela... View full abstract»
