    A catalog of improvements to the received signal-to-noise ratio of UHF-television signals is presented, indicating that an overall improvement of 16 dB may be possible. Implementing some or all of the possibilities for improvement could have major benefits to the reception of UHF signals, although the UHF-television industry, appears to be maturing into a successful service in spite of its disadva...

    The development of television broadcasting in Europe is outlined, with particular reference to the circumstances in which operation in the UHF band was introduced. The principles of frequency-assignment planning, together with their application in the case of UHF television, are then described. Attention is drawn to the factors taken into account in the preparation of an internationally agreed fre... View full abstract»

  • The effect of viewer behavior on reception and viewing of UHF television

    Publication Year: 1982, Page(s):1277 - 1293
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2681 KB)

    The effects of viewer behavior on the reception and viewing of UHF television are explored. By integrating the results from three new studies sponsored by the Federal Communications Commission's UHF Comparability Task Force with previous work it is possible to distinguish between factors that significantly influence UHF viewing and those which do not. The three new studies are: 1) a large public o... View full abstract»

  • UHF transmitting facilities design

    Publication Year: 1982, Page(s):1293 - 1299
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4360 KB)

    Many factors influence the design of an effective UHF-television transmitting plant. Site and antenna selection, and their optimization, are particularly critical, while the design of the plant itself has a significant influence on the overall reliability of the system. Several factors relating to the design of an effective transmitting plant are discussed and suggestions offered to minimize insta... View full abstract»

  • Circularly polarized UHF-TV transmission

    Publication Year: 1982, Page(s):1300 - 1303
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3389 KB)

    The reasons for choosing circularly polarized transmission for two new high-power UHF-television-transmitting stations are described and the results of the data so far obtained are summarized. Subscription television (STV) applications permitted the use of circularly polarized receiving antennas at subscriber locations, thus maintaining the circularly polarized nature of the system.

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5158 KB)

    The history of television klystrons is described, as are the features of modern television klystrons. Advantages of internal-cavity and external-cavity klystrons are compared. Bandwidth theory and the theory of klystron efficiency, which are matters of particular importance in this application, are also reviewed. View full abstract»

    Publication Year: 1982, Page(s):1312 - 1318
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1094 KB)

    The use of electron-beam modulation in klystron amplifiers is an important means of reducing the electrical power consumption of ultra-high-frequency power amplifiers, employed in the transmission of television signals. This paper explores the characteristics of the amplifiers, describes the methods developed for applying video modulation, and gives details of typical power savings which can be ex...

  • The klystrode—An unusual transmitting tube with potential for UHF-TV

    Economic considerations, especially the increasing cost of energy, have forced electron power tube designers to revise current designs and to re-examine old ones. One result of this re-examination is the rebirth and improvement of a very old and largely forgotten device which appears to hold great promise as a generator of tens to hundreds of kilowatts in the UHF range, with special advantages in ...

    Well performing multistage depressed collectors (MDC's) have been developed for traveling-wave tubes (TWT) in an sizes fitting the requirements of wide-band countermeasures, radars, and ground and space communications. In the case of NASA-type symmetric collectors, rigorous analytical tools were developed that permit accurate a priori designs of MDC's for any given helix-type tube. Although only f...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2819 KB)

    Cost effectiveness of high-power UHF-TV transmitters was and is directly linked to the selection by both broadcasters and equipment manufacturers of the main components for the high-power stages of these transmitters. While solid state is making significant inroads at low power, the most adequate component above 1 kW in UHF remains the electron tube. In the 1- to 25-kW range, the cost of energy as...

    We have devised a new iterative technique to improve the Extended Boundary Condition Method (EBCM) frequently used to solve for the scattering and absorption by lossy dielectric objects. This technique has two main features: 1) it requires an initial assumption of the external surface fields, and 2) it partitions the interior of the object into a number of overlapping subregions, thus assuring a m...

    This letter proves that the conductivity measuring technique presented by Rehman-Murti can be directly derived from the Van Der Pauw's method by a simple transformation of the current field. Hence, conclusions obtained for one method can be transposed to the other one. It is also proved that the Rehman-Murti structure can also be applied to Hall mobility measurements.

    An algorithm is presented for the determination of temperature at any time and at any interior point of a plane metallic body, given the surface heat flux. Alternatively, given the temperature at a specific point and time in a plane semi-infinite metallic body, with little or no assumed surface heat loss, the surface heat flux can be determined. The technique can be used to estimate open-circuit t... View full abstract»
