    Attention is called to the principal difference between the present success of audible pictures and the failures which preceded it. The similarities and differences between broadcasting and audible pictures are pointed out. This includes a comparison of the installations, a comparison of the pickup and reproduction conditions, etc. Some of the advantages of disk recording are pointed out. Measurem...

    This paper deals briefly with (1) the desirable characteristics of measuring equipment employed in making the usual tests of radio receiver performance and (2) a description of apparatus and technique used in carrying out several special tests. Measuring equipment and methods are discussed with reference to the elements of the receiver, after which are remarks on the usual tests of sensitivity, se... View full abstract»

    Operating characteristics of compact, dry, electrochemical, high-voltage filter condensers, comprising a dielectric plated sheet electrode contacting with a gummed spacer rolled with an untreated electrode sheet, show that such condensers are in all respects suitable for power-pack filter service and effect large reduction in costs. Commercial condensers of this type have working voltages up to 70... View full abstract»

  • Fluctuation Noise in Radio Receivers

    This paper discusses fluctuation noise in radio receivers due to shot and thermal effects (Schottky) in the radio-frequency circuits. The r-f noise components beat with the carrier when a signal is being received and are transformed to audio components which are heard as a hissing noise. The mathematical theory for a receiver employing a square-law detector is given, and it is shown that the defle... View full abstract»

  • A Screen-Grid Voltmeter and Its Application as a Resonance Indicator

    Publication Year: 1930, Page(s):1388 - 1395

    A screen-grid voltmeter of high sensitivity is described and compared with a triode voltmeter. At low frequencies, using either the 222 or the 224 tube, it effectively covers a range of from 0.1 to 10 volts, r.m.s. At frequencies of the order of 108cycles per sec., it serves as a supersensitive indicator for a Lecher wire system. For this purpose a tuned input is used. View full abstract»

  • Reflection of Radio Waves from the Surface of the Earth

    The reflection of an elliptically polarized electromagnetic wave from partially conducting and perfectly conducting surfaces is studied in detail. It is shown that in either case the interference of incident and reflected waves gives rise to a pseudo-stationary wave field above the surface of the reflector. This field is bodily propagated along the horizontal projection of the direction of the inc... View full abstract»

    A systematic scheme of classification of subjects in radio science and engineering is necessary in classifying references to current radio publications and also for classifying all sorts of other radio material, such as reports, reprints, drawings, books, apparatus, etc. In an effort to fill the need for a radio classification this extension of the Dewey decimal system was prepared. Since the publ... View full abstract»
