    The communications companies are often faced with the problem of increasing their facilities and occupying more efficiently existing channels, usually by the installation of new transmitters. To take advantage of existing equipment, use has been made of diplex (two messages in one direction), employing one transmitter whose output was commutated from one frequency to another at a rhythm superior t...

    Although the term "intermodulation" has been used for a long time to describe a form of distortion, only recently has simplified testing equipment been made available which permits the commercial testing of audio, radio, and general sound-recording equipment by this method. In this paper there is described a compact piece of apparatus which is being used for routine maintenance tests on the sound ... View full abstract»

    By following a simple analysis, it is shown that there are three cases for which optimum operating conditions may be established for class A amplifiers. These are for (I) the small signal, (II) the fixed quiescent plate voltage, and (III) the fixed quiescent plate dissipation. There is a "best" operating condition, which might be considered as a fourth case, if both the quiescent plate voltage and... View full abstract»

  • General Amplitude Relations for Transmission Lines with Unrestricted Line Parameters, Terminal Impedances, and Driving Point

    Subject to no other restrictions and approximations than those actually implied in the derivation of the transmission-line equations and their application to a terminated line, general expressions in simple form are derived for the current amplitude in, and the potential difference between, the two conductors of a uniform transmission line at any point along its extension. The terminal impedances ... View full abstract»

  • Civilian Receiver Design in 1942

    While obviously not of direct combat use, the propaganda, social, and economic contribution to the cause places civilian radio strategically in the defense program. A minimum of 7½ million such receivers are needed annually to maintain a satisfactory morale-building propaganda machine. The engineer has a rare opportunity to contribute handsomely to the expedition of this work. Such a program ... View full abstract»
