    This paper describes a single-gun cathode-ray display system (the Apple System) for color television receivers based on the phenomenon of secondary emission. An index signal, derived from a secondary emissive structure built into the screen of the tube, continuously indicates the position of the scanning spot relative to the color phosphor structure. This positional information is combined with th... View full abstract»

    This paper describes the Apple color picture tube, its dimensions, materials of construction, deflection and focus systems, and the geometry and deposition of the phosphor and secondary-emissive screen materials. The construction and operation of the electron gun, which produces two independent beams of very small cross section from a single cathode, are described in detail. Life test data and pil...

    This paper reviews the components and circuits of a developmental color television receiver utilizing the Apple type of display. The block diagram of the complete receiver is presented, together with detailed diagrams of circuits peculiar to the display, i.e., the index signal amplifier, color signal processing, high-voltage, horizontal sweep, and focus circuits. Photographs of the chassis layout ... View full abstract»

    This paper discusses possible directions of improvement in the NTSC color television standards. These are aimed at minor modifications of the transmitted signal which allow the use of simpler color receivers with more accurate resolution in colored areas. Compatibility also appears likely to be improved by one of the features presented, that is, monochrome receivers would display improved picture ... View full abstract»

  • A Precise New System of FM Radar

    Publication Year: 1956 , Page(s): 1140 - 1145

    The paper describes a new system of fm radar by which both the range and the speed of the target can be accurately measured. The "fixed error," which is a characteristic of fm radar apparatus now in use, has been eliminated, affording correct measurement of ranges, even if they are very short. The functioning of the new system has been investigated experimentally and proven to be very successful. ... View full abstract»

  • Maximum Angular Accuracy of a Pulsed Search Radar

    Publication Year: 1956 , Page(s): 1146 - 1155
    Cited by:  Papers (22)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (2397 KB)  

    An investigation is made of the limits imposed by receiver noise on the accuracy with which the angular position of a target can be determined by a pulsed search radar. Using a result in the theory of statistical estimation, a lower bound is derived for the standard deviation of regular unbiased estimates of target angular position, for a large class of methods of angular position determination; t...

  • An 8-mm Klystron Power Oscillator

    Publication Year: 1956 , Page(s): 1155 - 1159
    Cited by:  Papers (5)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (1967 KB)  

    The development of a cw klystron oscillator as a low-noise transmitter for the 8-mm band is described, and details are given of its performance. The power in the electron stream is 350 watts (0.1 ampere at 3,500 volts) and the output power 12 w. Special features include a design for a bakeout temperature of 700°C, using molybdenum-sealing aluminosilicate glass, and a high convergence electron-opt... View full abstract»

  • Restrictions on the Shape Factors of the Step Response of Positive Real System Functions

    Given the maxium size of any overshoot or under-shoot of the step response of a network whose system function is positive real, a lower bound on the rise time from zero to the final value is developed. Similarly lower bounds on the settling time are also derived. These results are improvements over previously published results. They are special cases of a general theorem which bounds the unit step... View full abstract»

    The design, fabrication, and electrical characteristics of silicon p-n-p-n transistors with ¿>1 for use as switches is discussed. The increase of alpha with injection level can be used to construct two terminal p-n-p-n switches. The high impedance characteristic has an impedance determined chiefly by the capacitance of the junctions. This capacity is of the order of tens of micromicrofarads. The ... View full abstract»

  • Two-Terminal P-N Junction Devices for Frequency Conversion and Computation

    Design principles for semiconductor diodes are derived from the analysis of idealized p-n junctions. The analysis gives the superheterodyne conversion matrix and the large-signal admittance in terms of the small-signal diffusion admittances. Structures that minimize minority-carrier storage give minimum conversion loss under matched conditions in converting a high frequency to a low frequency, and... View full abstract»
