    Several programs planned by the military have required that the audio bandwidth of the radio circuit be much wider than that required for voice communication. In these applications, it is also necessary to maintain a much higher degree of continuity of communications and freedom from fading than had been necessary for the voice circuits. Each of these changes has indicated a need for much higher p... View full abstract»

    The author takes an objective look at how telecommunication has been, is, and will probably be used by air transportation. It is recommended that private enterprise implement the communication framework for use jointly by the government and nongovernment agencies. The feasibility of that rrecommendation appears evident; existing land line plant facilities of the nation furnished by private enterpr... View full abstract»

    One of the vital requirements for safe and efficient control of traffic is the communication link between the controller and pilot. When the US Civil Aeronautics Administration (CAA) first started operating control towers, around 1940, the towers had a single operating poeition which guarded two or three high frequency channels and transmitted on a low frequency channel. Since World War II, most o... View full abstract»

  • Consideration of mechanical and LC type filters

    Publication Year: 1956, Page(s):54 - 57
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (598 KB)

    In comparing the usefulness of various filters for a given device, the design engineer is confronted with many questions. In most instances these questions can be answered readily because of predominance of a performance requirement for which alternate solutions are not available. In other instances, however, there may be several suitable solutions. The designer will then have to decide on the bas... View full abstract»

    The performance characteristics of any filter may be entered onto a graph of the amount of resonant elements vs. either shape factor or the Q's of the individual resonant elements. If curves of various design styles are also drawn on these graphs, one may compare how nearly a particular filter approaches the theoretically best performance for its style. Such curves are presented for typical filter... View full abstract»

    Where digital systems are used, it is frequently desired to store bits of information, temporarily. This is often necessary when other operations such as checking, are occurring. Following temporary storage, it is then often desired to place the information in long-time storage in the form of open and closed switch contacts. The methods and equipment now used Bre expensive, bulky and complex. The ... View full abstract»

    Thls paper gives a general description of a single sideband communications system which is presently being developed for the US Air Force. It was written early in the progress of the development, and hence, certain of the detailed descriptions as given will change as the program approaches maturity. The program is intended to provide more reliable HF communications by exploiting Single Sideband te... View full abstract»

    The communications capacity required of the Common System for the year 1965 is projected from figures of fix postings for 1946 and 1954. In 1946, 8,800,000 fixes were reported; in 1954, 16,900,000 fixes were recorded. If this trend continues, the forecast for 1965 is 1,100,000 instrument approaches, and 32 million fix postings! Additionally, there are new requirements to be considered for the 1965... View full abstract»

    Radio interference suppression must be considered in early design stages for maximum effectiveness. The chief sources of interference to communication systems are spurious and harmonic radiations, corona and precipitation static, and co-channel and adjacentchannel interference. Other interference sources such as ignition systems, rotating machinery and contacting devices are not included in the sc... View full abstract»

    Difficulty in satisfying increased requirements for aeronautical communication channels appears to justify investigating the potentialities of various means of submarine cable communication as a means of easing the burden on long radio links. Relief might be found by using submarine cables to connect strategic and widely separated land stations and thus materially reduce the length of radio links ... View full abstract»
