    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3032 KB)

    The application of radiotelephony to municipal police work in New York City is described from the organization viewpoint. Brief references are made to historical backgrounds and description of apparatus, and the steps taken to select a receiver suitable for local conditions are outlined. The method of controlling the patrolforce by radio is described at some length with examples, and a summary of ... View full abstract»

  • An Outline of the Action of a Tone Corrected Highly Selective Receiver

    Publication Year: 1933, Page(s):1252 - 1264
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1072 KB)

    The action of a highly selective simple tuned circuit located between a source of radio-frequency energy and the terminals of a detector is discussed. Next, the effect of linear and of square-law detection together with an audio-frequency tone correction system is described. Various interference conditions are analyzed with the aid of graphical construction. View full abstract»

    The present paper gives the practical results of an extensive analysis of the detection of two modulated waves of identical carrier frequency. It is shown that the total effects of time delay in the program distribution circuits, differences in circuit elements in the two transmitters, and differences in path lengths of the two signals in traveling from their respective transmitters to the receivi...

    A receiving equipment and calibration method is described for the measurement in absolute units of 5.1-meter (58.8-megacycle) field strengths. A transmitter of low power is used. The attenuation of the waves is discussed, and a field strength contour map of Ann Arbor, Michigan, and vicinity is presented. The attenuation constant is found to be 0.36. Experiments on receiving antenna lengths show th... View full abstract»

    This paper describes a qualitative study of the degrees of television definition required for the adequate portrayal of various scenes under various conditions. Still photographs transmitted by telephoto are examined. It is found that 60-line, 120-line and higher orders of television definition may be suitable for certain missions conditioned by general factors such as the comprehensiveness of the...

    A rod of monel metal supported at its mid-point and fitted with two coils, one on each end, shielded from each other, and supplied with a polarizing magnetic field, resonates sharply at its natural longitudinal frequency to a voltage impressed on one coil, and induces a voltage in the other only while vibrating. It is thus a very selective band-pass filter. The attenuation is more than sixty decib... View full abstract»

    An expression for the radiation resistance of a cylinder is derived, following the "tangential field" or "induced electromotive force" method as adapted by Pistolkors. The result is used to determine the radiation resistance of a segment of a concentric cylinder transmission line, as used in ultra-high-frequency oscillator circuits. A comparision is made with the more conventional parallel wire li... View full abstract»

    This report gives the monthly and annual averages of field intensities of ten European and three American low-frequency transatlantic radio stations, between frequencies of 16 and 24 kilocycles, and the field intensity averages of atmospherics on 15 and 23 kilocycles, observed at the Bureau of Standards, for the years 1931 and 1932. Measurements were made by the telephone current comparison method... View full abstract»
