    Upon this, the Silver Anniversary of the Institute of Radio Engineers, it is appropriate to recall how there came into being the art of radiotelephony and, in turn, such services as overseas telephony and broadcasting. The Institute has seen the entire evolution within its relatively short life, with radiotelephony an unsolved problem in 1912 and today an accomplished fact of world-wide applicatio...

    Marking the tenth anniversary of the beginning of commercial long-distance radiotelephone service, the paper reviews: (1) Technical advances over the older radiotelegraph and short distance radiotelephone arts which made the initiation of long-distance service possible. These included water-cooled tubes, single-side-band suppressed-carrier transmission, and voice operated switching devices designe... View full abstract»

  • Notes on Some Practical Comparison Tests Made between Several Acoustic Measurement Methods

    Publication Year: 1937 , Page(s): 1136 - 1152
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1976 KB)  

    In considering the various methods used in making over-all acoustic measurements on radio receivers, from the standpoint of possible standardization, it was felt desirable to make a comparison of the results obtainable by the several principal methods now in use in this country. Accordingly a radio receiver was shipped successively to five different laboratories equipped to make such measurements.... View full abstract»

    Constantly increasing demand for synchronizing devices in telecommunication techniques has involved extended use of devices for the production of harmonics and subharmonics of an input master frequency. This article describes a new circuit for a generator by means of which frequency multiplication and division can be obtained The principle of feedback is applied in a new way to a valve circuit hav...

    Evidence is presented which indicates that, notwithstanding the change in sign made by Sommerfeld in his 1926 paper on radio wave propagation, the radiation field of a vertical electric dipole may be separated into space and surface wave components. Sommerfeld's original concepts as to the characteristics of two such waves in radio transmission are largely substantiated. It is shown that a space a... View full abstract»

    Completely general formulas are given for computing at any point above a plane earth of finite conductivity the vector electric field for a source which may be a combination of vertical and horizontal electric dipoles or a loop antenna with its axis parallel or perpendicular to the earth. As illustrations of the above general methods, formulas are derived for the ground-wave radiation from (1) a g... View full abstract»
