    Three approaches to modelling FM video spectra which include energy dispersal are described. The first method is an analytical approach minimizing computer processing time. The second gives a more complete solution using numerical methods. In the third approach a statistical model is proposed with particular application to interference analysis. Each approach has both advantages and disadvantages,... View full abstract»

    Two methods of sun outage avoidance in satellite television transmission are discussed. Each method requires two satellites and dual-beam antennas. The two C-band satellites transmit identical programs at the time when the sun outage period occurs. The separation of the spacecraft is dependent on the dual-feed earth station antenna size. For large television receive-only antennas, the sep... View full abstract»

  • A new and systems oriented method of directional antenna tuning

    Publication Year: 1988, Page(s):63 - 69
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (488 KB)

    The AM antenna tuning method presented takes into account and absorbs stray inductances and capacitances, and mutual coupling between components with very high initial adjustment accuracy. Besides an antenna monitor and a field strength meter, the equipment used for tuning consists of a high-precision reflectometer, a spring-loaded and side-handled split toroidal clamp-on ammeter, and a Hewlett-Pa...

    Results are presented of computer modeling studies indicating that an elevated vertical monopole antenna with four elevated horizontal radials produces more ground-wave field strength than does a conventional ground-mounted monopole with 120 buried radials. For the analysis, the length of the radials and the height of the monopole were set equal to 0.25 of the free-space wavelength, and the freque... View full abstract»

  • Novel dielectric-waveguide components

    Publication Year: 1988, Page(s):2 - 8
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (480 KB)

    A variety of resonators and bandpass, notch, lowpass, and highpass filters are described that use dielectric materials of high permittivity and are based on conventional waveguide technology. The devices are reasonably small, of high Q, and low loss tangent (tan δ). The various configurations presented include the use of posts, inductive strips, waveguide resonator-filters, and re-e...

  • Ground loss effects in power line reradiation at standard broadcast frequencies

    Publication Year: 1988, Page(s):24 - 38
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1292 KB)

    Reradiation of a standard broadcast antenna's signal from a high-voltage power line is often analyzed by computer modeling. The resonant behavior of a power line operating over lossy ground is investigated using the numerical electromagnetics code (NEC) which uses the Sommerfeld-Norton (SN) ground model, for a highly accurate computation of the interaction of a power line with lossy ground. It is ... View full abstract»

  • Fitting graphs and numerical tables for a single parameter representation of the shape of programme sound signal distributions

    Publication Year: 1988, Page(s):9 - 17
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (688 KB)

    In order to represent the statistical character of a sound signal simply and with a single parameter, numerical tables and graphs of theoretical distributions for the estimation of a parameter called the shape parameter of the distribution are presented. The theoretical distributions are based on a statistical model of broadcast signals which was derived from the analysis of variations in measured... View full abstract»

  • Modelling a standard broadcast directional array with the numerical electromagnetics code

    Publication Year: 1988, Page(s):39 - 49
    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (816 KB)

    The numerical electromagnetics code (NEC) is a general-purpose wire-antenna-analysis computer program capable of modelling both a standard-broadcast directional array (DA) and a scatterer such as a power line. The starting point for such a study is a NEC model of the directional array itself. The DA's admittance matrix could be used to choose voltage excitations for the NEC model such that NEC's t...

    Subcarrier audio channels (SCAs) are used to support a wide-area data communication system. Text or data messages can be transmitted nationally using satellite delivery, and locally using FM broadcasting stations' subcarriers. The time delay that messages experience in the national buffer at the satellite head-end or the local buffer is examined. The delay for various throughput data rates is eval... View full abstract»

    A description is given of the history of New Jersey Network (WNJN, the New Jersey state public television system), the decision to convert the system to MTS stereo, the goals of the technical improvement program, and representative test results. The author discusses origination, production, switching, microwave relay systems, transmitter conversion and interfacing, and off-air monitoring facilitie... View full abstract»
