    After a review of the various electronic techniques which have been used in television to simulate optical effects used in motion picture photography, a new process called "Chroma-Key" is described. "Chroma-Key" is an insetting or matting technique intended for color television which utilizes a highly saturated color background for the inset subject. Many of the problems normally associated with m... View full abstract»

    The feasibility of displaying images according to electrical signals using an array of electroluminescent cells magnetically controlled has been demonstrated by a working model. A transfluxor is associated with every electroluminescent cell. Each transfluxor is set by the coincidence of row and column current pulses to a level determined by the amplitude of the video signal, stores this level, and... View full abstract»

  • Incoherent Scattering of Radio Waves by Free Electrons with Applications to Space Exploration by Radar

    Publication Year: 1958 , Page(s): 1824 - 1829
    Cited by:  Papers (15)

    Free electrons in an ionized medium scatter radio waves weakly. Under certain conditions only incoherent scattering exists. A powerful radar can detect the incoherent backscatter from the free electrons in and above the earth's ionosphere. The received signal is spread in frequency by the Doppler shifts associated with the thermal motion of the electrons. On the basis of incoherent backscatter by ... View full abstract»

  • Analysis of Millimicrosecond RF Pulse Transmission

    Publication Year: 1958 , Page(s): 1830 - 1835
    Cited by:  Papers (17)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1134 KB)  

    An analysis of millimicrosecond RF pulse transmission through uniform systems is presented. Quadratic approximations for the complex propagation constant are used, and a Gaussian pulse envelope is assumed. Employing Fourier transformation, the received waveforms are obtained for the general case of lossy, dispersive systems. The results are discussed and illustrated separately in terms of pulse di...

  • A Quartz Servo Oscillator

    Publication Year: 1958 , Page(s): 1835 - 1841

    The paper deals with a 5 mc oscillator whose frequency instabilities due to vacuum tube effects are at least 100 times less than those present in the best conventional oscillators which achieve stabilization by resonant vector balance. By using quartz crystals of low drift, it is therefore possible to reduce unpredictable frequency changes to one or two parts in 1010. The tubedependent instabiliti... View full abstract»

  • Some Generalized Scattering Relationships in Transhorizon Propagation

    An analysis is made of the consequences to be derived from some fairly broad assumptions as to the nature of turbulent scattering and its effect on waves propagated through the troposphere. The intent is to provide a means for testing the general applicability of this model as an explanation for transhorizon propagation. General relationships for the variation of received power with distance are d... View full abstract»

  • A Very-Wide-Band Balun Transformer for VHF and UHF

    Publication Year: 1958 , Page(s): 1848 - 1860
    Cited by:  Papers (2)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2462 KB)  

    A transformer is described which may be used as a phase inverter, a differential transformer, or as a balun transformer. Practical models have been built which operate over more than two decades of frequency range with bandwidths approaching 1 kmc. Insertion loss in a typical transformer fluctuates between 1 and 2 db over the range of frequencies from 5 to 1000 mc. For successful operation the tra... View full abstract»

  • Nomographs for Designing Elliptic-Function Filters

    Publication Year: 1958 , Page(s): 1860 - 1864
    Cited by:  Papers (5)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (834 KB)  

    The elliptic-function filter is of considerable importance because of its ability to provide simultaneously small pass band ripple, large stop band attenuation, and very sharp cutoff, with equal-ripple behavior in both the pass band and the stop band. The fundamental design parameters are the pass band ripple, the stop band attenuation, the transition bandwidth, and the number of poles required. T... View full abstract»

    The annular geometry gun represents a distinct departure in electron gun design and operation. The modulator section contains an annular cathode, annular control grids and accelerating grids, a beam bending probe and an electron object electrode. Very high modulation sensitivity, inverted modulation characteristics, internal electronic video signal amplification, and automatic "white noise" invers... View full abstract»
