    Very soon after Alexander Graham Bell invented the telephone, it became obvious that it would be impractical to extend wires from every telephone to all other telephones. To conserve copper and dollars, wires had to converge on central points where individual telephone-to-telephone connections would be made. In this paper we will describe many significant changes in the Bell System network from th... View full abstract»

    Microwave telecommunications transmissions from the two Voyager spacecraft are being used to make detailed studies of planetary atmospheres, ionospheres, rings, and magnetic fields in the outer solar system. Coherently related sinusoidal signals, at wavelengths of 3.6 and 13 cm, transmitted from Voyager but received and analyzed on Earth serve as an active probe of planetary environs. Such studies...

  • Use of a surface-acoustic-wave (SAW) device to monitor etching of thin films

    The use of a surface-acoustic-wave (SAW) device to monitor etching of thin films is described. The device is a delay-line-stabilized SAW oscillator in which the propagation path is coated with a thin film of the material to be etched. Removal of material decreases the mass loading on the delay line and this increases the frequency of the oscillator. The frequency of a 75-MHz oscillator is found to... View full abstract»

  • Transient mean and variance of overflow traffic in a loss system

    Publication Year: 1987, Page(s):1435 - 1436

    Simple techniques to approximate the mean and variance of the overflow traffic in a telephone system are outlined. The mean is first approximated, and by using the peakedness value obtained via the interrupted Poisson process, the variance is then approximated. View full abstract»

    The regenerative receiver [1] and the synchronous oscillator (SO) [2]-[4] have one common functional property, that is, their sensitivity is inversely proportional to the input signal level While the regenerative receiver operates in a threshold condition where noise is high, the stability and the selectivity are poor, the SO functions when stable oscillations are maintained and selectivity is goo...
