    This paper is a continuation of work reported in the Proceedings of the Institute of Radio Engineers for May 1928 by the same authors. A more extended study of echo signals with particular reference to directional characteristics and to diurnal variations has been carried out. Attention has also been given to the question of the relations between the echo signal and the frequency. Distortions, pro... View full abstract»

  • Group-Velocity and Long Retardations of Radio Echoes

    Van der Pol's hypothesis that group-velocity may account for the retardation of echoes observed by Stoermer is analyzed. It is shown that only under very special circumstances can the electron-distribution be proper. A favorable condition is obtained if the refractive index decreases exponentially with the height. It is shown that by slightly varying the electron-distribution anomalous results for... View full abstract»

  • Further Studies of the Kennelly-Heaviside Layer by the Echo-Method

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4072 KB)

    Recent observations of the Kennelly-Heaviside layer by the echo-method are described. Multivibrator-modulation was used, giving extremely sharp "peaks" on 4,435 and 8,870 kc. Practically all of the observations were made on the former frequency, as 8,870 kc skipped over the receiver, which was very near the transmitter. Two 24-hour series of observations showed a marked diurnal-variation in the ef... View full abstract»

    Assuming that the atmosphere at the surface of Mars consists of ⅕ oxygen and ⅘ other gases, as nitrogen, etc., the composition of the atmosphere to great heights is calculated, just as was done for the earth, from the actions of gas diffusion and gravity. The electron density in the atmosphere of Mars due to the ultraviolet light of the sun is found to have a maximum value of 1.1 ×... View full abstract»

    The objective of this paper is a discussion of some of the important principles underlying the electrical transmission of pictures rather than a description of detailed methods by which such transmission may be effected. The subject, which includes both still pictures and television, is treated as a special form of electrical communication, differing from other forms primarily in the nature of the...

    The basis of a system of television standards suitable for commercial television service, with specific standards, is discussed. The elements considered in this paper are the following: picture proportions, number of scanning elements, number of picture repetitions per second, scanning method and direction, phase of transmitted current. Synchronizing is considered, with possible methods, and also ... View full abstract»

    The paper contains a discussion of the causes and effects of microphonic disturbances in small receiving tubes and the nature of these disturbances, and gives methods of testing for microphonic disturbance whereby the sources of the disturbance may be located and corrected, as well as methods of testing tubes as a means of comparison of individual tubes of different types. A new type of tube with ... View full abstract»

  • Equivalent Circuits of an Electron Triode and the Equivalent Input and Output Admittances

    This paper is presented in two parts. In Part I two fundamental equivalence theorems concerning a triode and its circuits are rigorously derived. These theorems give the simple circuits which are equivalent to the plate and grid circuits of the triode. These equivalent circuits contain only constant circuit elements and fictitious electromotive forces, the use of which greatly simplifies the calcu... View full abstract»
