    In this paper we are comparing from a theoretical standpoint the methods of attainment of the highest degree of selectivity required by present broadcasting conditions, and investigating the distortions introduced by receivers employing such methods in practice. The equations for magnification and phase differences introduced by one or more simple tuned circuits are first obtained in a convenient ... View full abstract»

  • Linear Distortions in Broadcast Receivers and Their Compensation by Low-Frequency Equalization Devices

    This paper shows how the selectivity as well as the processes in the detector and low-frequency part cause distortion in broadcast receivers. The chief cause of poor fidelity must be sought in the selectivity of the tuning means. This can be raised to high values by increasing the number of tuning circuits, and by improving the quality of the coils (sharpness of tuning). The need for many selectio... View full abstract»

    This paper reviews some of the principles of dynamic symmetry, the science of vital relations of areas, which was the basis of ancient Greek art, as rediscovered by Jay Hambidge about fifteen years ago, and described in his works "Dynamic Symmetry" and "The Diagonal," published by the Yale University Press. A list of the most important shapes is given, and diagrammatic examples of them, which are ... View full abstract»

    A relation between atmospheric noise intensity and frequency is estimated upon the basis of noise measurement data covering the frequency range between 15 and 60 kilocycles, and 2 and 20 megacycles. View full abstract»

  • Current Rectification at Metal Contacts

    Six different contacts of dissimilar metals, namely Cu-Fe, Cu-Sn, Sn-Zn, Zn-Fe, and Pb-Sn, were studied for their rectifying properties. As far as possible small lengths of cylindrical rods with circular section were used. Their tips barely touched each other producing an imperfect contact at which rectification was found to take place best. In all cases, static characteristics showed that when th...
