    The phase and magnitude characteristics of five network functions, all three-pole approximations to an ideal low-pass filter characteristic, are compared. The functions considered are the Butterworth, Chebyshev, Papoulis Class L, `maximally flat delay¿ and `in-line pole¿; all of these can be realized with a simple passive circuit. The equations for the pole locations are quoted. Plots of the pol... View full abstract»

    A synchronous system is described which transmits binarycoded digital-information at 750 or 1500 bauds over normal telephone circuits. It uses a phase-modulated carrier of 1500 c/s and both sidebands are transmitted. The receiver employs differentially-coherent detection to overcome the one serious weakness of coherent detection, which is the low tolerance of the latter to the frequency-modulation...

    The equipment provides an accurate method of multiplying a frequency by M/N, where M and N are integers and M ¿ N. Two batching counters are used to determine the output frequency in the long term and the equipment described restores the correct phase relationship. The equipment is transistorized and makes use of modern techniques for counting, gating and parallel addition and subtraction. A brie... View full abstract»

    The distribution of pay television programmes by wire eliminates coding and decoding equipment required for an over-the-air system in order to prevent unauthorized reception. An outline is given of the advantages of h.f. multi-pair type networks in this and other respects. Two wired systems of pay television are described, and some factors which have governed their development are discussed. View full abstract»

    The paper deals with electronic computing devices intended to fill the gap between the more complex mechanical calculators and the simpler forms of general purpose electronic computer. After a discussion of design considerations, the overall concept of a particular solution to this problem is described, with some details of the resulting equipment. Some configurations suitable for known applicatio... View full abstract»

  • The telephone channel capacity of transmission lines

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (734 KB)

    The attenuation of transmission lines used for telephone transmission varies very nearly as the square root of frequency when dielectric loss is small and conductor resistance is controlled by skin effect. In this paper the maximum number of telephone channels which can be obtained on such a line using a.m.-f.d.m., f.m.-f.d.m., and p.c.m.- t.d.m. is calculated as a function of line attenuation at ...

  • Analysis of series regulators as active two-port networks

    Regulators for regulated power supplies are here treated as active two-port networks. To characterize the performance, two parameters: the regulation factor R and the internal impedance Zoutare defined for the ideal case of infinite load impedance and zero source impedance of the unregulated side. A general theory is developed and specific circuit arrangements are shown to be particular cases of t... View full abstract»
