    Frequency assignments to particular broadcasting stations within the range 150-1500 kHz are now made on the basis of empirically derived sky wave propagation curves that are used to determine the service and interference field strengths of these stations. Using the concept of propagation loss, a detailed comparison is presented between two series of propagation curves used for this purpose in the ... View full abstract»

    In April, 1964, the Federal Communications Commission adopted new rules regarding visual to aural power ratios whereby a ratio as high as 10 to 1 was authorized. This offered some interesting possibilities for minor cost reduction in conventional transmitter manufacture, such as use of a high-power klystron in the visual stage and a low-power tetrode in the aural stage. On the other hand, the poss... View full abstract»

    An experimental ionospheric sounder has been constructed for vertical-incidence or oblique sounding in the frequency range 600 kHz to 2 MHz. The equipment employs an FM linear frequency sweep transmission generated by direct synthesis from a frequency standard; an identical sweep is used for demodulation at the receiver. Sounding records, made at night over a 2000-km path, exhibit 10-μs re... View full abstract»

  • Level Adjustment of Audio Signals by Means of a Solid-State Electronic Attenuator

    Publication Year: 1966, Page(s):30 - 37

    A solid-state centralized system of level adjustments of audio signals is described. The problem considered was how to adjust and vary the level of audio signals with the same precision achieved with present mechanical step-attenuators. The method finally decided upon was that of using the variable-impedance characteristic of a forward-biased diode. The diode impedance decreases proportionately to... View full abstract»

    There is a growing interest in technical performance specifications for Community Antenna Television (CATV) systems on the part of system operators, manufacturers, and governmental regulatory bodies. There is at present no accepted standard for such operations. This paper outlines the major elements involved in adequate specifications. Numerical performance standards are suggested in some cases; i... View full abstract»
