  • Phosphors and Picture-Tube Performance

    Page(s): 1 - 8

    The brightness, contrast, and sharpness of the picture on a color television tube screen is of great importance to the consumer and of major interest to the picture tube designer. Chromacolor has yielded a substantial improvement both in brightness (to over 100 ft-L) and in contrast (by absorbing incident ambient light) due to its negative guard-band, black surround construction. The sharpness of the picture on the screen depends largely on the diameter of the electron beam incident upon the phosphor dots. An improvement in sharpness can be brought about by a reduction in the size of the electron beam; however, such a reduction in diameter will result in an increase in current density. This brings up a question concerning the cathodoluminescence1 of these phosphors: is the emission intensity linear with respect to beam current density in the region of practical beam currents?

  • Wide-Angle Color Crt Deflection for Horizontal Linearity Correction

    Page(s): 9 - 14
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (5848 KB)  

    The horizontal deflection yoke current for TV displays tends to be nonlinear and normally requires correction. The correction voltage is required to vary abruptly just before the start of trace and thendecline during approximately the first one-third of trace. In the system discussed in this paper, the linearity correction voltage is superimposed on a capacitor. In order to conserve power, a feedback circuit makes this capacitor charging current flow back into the power source rather than being dissipated. View full abstract»

  • Computer -Aided Horizontal Sweep Design

    The element of Black Art often associated with television horizontal sweep system design may be reduced by resolving the complex system interactions through computer synthesis and analysis. The following procedure derives necessary physical system parameters based on specified desired operating voltages, tertiary tuning, and other physical system requirements. Once acceptable stress conditions have been realized the resultant computer derived design should require only slight "tweaking" to yield a workable system. View full abstract»

  • Statistical Analysis of Electronic Circuits by Computer

    Page(s): 51 - 56
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1146 KB)  

    The digital computer has firmly established itself as a useful tool in the solution of engineering problems. Perhaps one of the best examples of engineering computer utilization is in the area of statistical analysis of electronic circuits. This paper concerns itself with a particular digital computer program called PANE, (Performance ANalysis of Electrical Circuits) which has been sucessfully used to perform statistical analysis on a variety of electrical circuits [1]. PANE, originally written for the IBM System/360, has been modiffied somewhat to meet the ever increasing requirements of computer-aided circuit design. This means that circuit analysis programs must have the capacity to handle large and complex circuits, and yet do so, particularly in the case of statistical analysis, as economically as possible.

  • Electron Optics for CRT's: Computer Modeling

    The performance of electron guns can be improved with the aid of accurate visual models of the gun and beam, including thermal spreading and space charge effects, as previously described in the literature. To effectively model a CRT-type of electron gun, a "scaled" approach is outlined in which the region of the cathode and control grid is treated with greater accuracy than are the succeeding regions of the lens and field-free space. Using computer-drawn plots of the gun structure, field, and beam, the five steps needed to imploment this "scaled" approach are summarized. View full abstract»

  • Computing Colorimetric Errors of a Color Television Display System

    Page(s): 63 - 73
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1912 KB)  

    The colorimetric characteristics of a color television display system are determined by the display primaries, the display white color and the signals applied to the display device. FCC Rules and Regulations state that, for the color television system approved for broadcasting in the United States, the gamma-corrected R,G,B voltages used to form the composite color signal are to be suitable for a color picture tube having primary colors with NTSC chromaticity coordinates. The numerical values of the signal specification assume that the display white color will be CIE Illuminant C. (x = .310, y = .316) Most color picture tubes in use at present (1974) have phosphors whose chromaticity coordinates differ substantially from NTSC primaries. If the signals applied to such picture tubes are those formed by color decoding which is the inverse of NTSC encoding, substantial colorimetric errors will result. These errors can be reduced by a corrective matrix which may be introduced directly or by modifying the color decoding. View full abstract»

  • A Monolothic 4-Channel/Stereophonic Decoder for an FM Broadcast System With Pilots

    The General Electric Company has expanded the 2-channel FM stereo broadcast systeml into a discrete 4-channel system2,3,4, that is compatible with present day stereo and monaural receiver equipments. Future receiver systems designed to decode the discrete 4-channel signal must incorporate a low cost decoder which is also functionally compatible with monaural and stereo transmissions. Consideration in the design of the decoder include the format of the composite signal, desired performance levels, technology selection and cost. View full abstract»
