    There is described a method of radio transmission designed to economize frequency space in broadcasting, wherein one sideband and the carrier are transmitted, together with the lower audio-frequency components of the other sideband. By retaining the lower frequencies of the second sideband there is minimized the distortion to which pure single sideband gives rise in the types of broadcast receiver... View full abstract»

    The results of daily observations at Riverhead, L.I., N.Y., since September, 1938, of the English television transmissions on 41.5 and 45.0 megacycles are summarized and discussed. A photograph of one of the television images received during this period is shown. A résumé is made of the signal strengths observed since January, 1937. During each winter of this period signal strengths of b... View full abstract»

    This paper describes the technique of locating the apparent source of atmospherics employing several stations located at a considerable distance from each other and equipped with cathoderay-tube direction finders. It discusses the data obtained on six tropical storms and compares the results with the estimate of the positron of the storm center as reported on the daily bulletins of the United Stes...

    This paper presents a method of analyzing F2-region critical-frequency data in a way that shows in a clear-cut manner the correlation that exists between monthly average values of these critical frequencies for undisturbed days and solar activity as measured by the central-zone character figures for calcium flocculi. Curves are presented which show for each month the expected diurnal va... View full abstract»

    This paper considers the American radio industry from the standpoint of its long-time economic trends, with special reference to the past and probable future public demand for broadcast receivers and vacuum tubes. The history of the anuual sales to each of the various markets for these is analyzed, equations are given for their long-time growth trends, and estimates of growth are projected ahead t...

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2048 KB)

    The general problem of coupling between circuits which extend beyond the near zone is investigated theoretically. Integrals defining generalized coefficients of inductance are displayed and discussed for the case of the near zone and in general. As an application, the specific problem of determining the current distribution in two coupled circuits which extend beyond the near zone is examined, and... View full abstract»

  • Television Detail and Selective-Sideband Transmission

    Publication Year: 1939, Page(s):725 - 732

    Recently selective-sideband transmission has been adopted in this country in order to increase the picture detail which can be transmitted in a frequency channel of given width. The present analysis is an examination of the theoretical justification for this practice. The effect of various degrees of unequal-sideband transmission on typical television signals is calculated by Fourier integral anal... View full abstract»

  • The Anode-Tank-Circuit Magnetron

    Publication Year: 1939, Page(s):732 - 738

    A new type of magnetron is described in which the split cylindrical anode is made approximately one-quarter wave in length, the two segments being short-circuited at one end. The anode resonates and acts as a tank circuit. Thus difficulties due to interelectrode capacitance and tube lead inductance are circumvented and a much greater heat radiating area is provided. An output of 20 watts at 3750 m... View full abstract»
