    A new data transmission technique has been evolved, which has the speed capability of the quaternary systems and, at the same time, promising performance. An important advantage of this technique is that the amount of circuitry required and the degree of complexity are relatively low, being not much more than for a straight binary system and much less than for a typical quaternary system. The proc... View full abstract»

    THE THIN-wire loop is one of the first antennas to receive theoretical consideration, having been discussed by Pocklington1 in 1897. Pocklington treated a closed loop excited by a plane wave; he obtained an exact solution for the current on the loop in the form of a Fourier series. More recently, Hallén2 considered a driven loop and obtained a solution, again in the form of a Fourier series, for ... View full abstract»

    A magnetic frequency tripler is a nonlinear magnetic system which is used for the production of triple-frequency output from a 3-phase fundamental frequency source. Although triplers have been used extensively for certain applications, the design of these devices has until now been largely empirical. Earlier papers1,2 have presented limited analyses of magnetic frequency-tripling devices and the a... View full abstract»

    The effects of amplitude distortion are frequently of considerable importance in the design of transistor feedback amplifiers. The analysis of distortion in a transistor amplifier is inherently more complex than in the vacuum-tube counterpart because of two factors. First, the transistor has an input conductance which is nonlinear and of appreciable magnitude in the normal operating frequency rang... View full abstract»

  • Signal-to-noise ratios in strong-carrier FM systems

    Signal-to-noise ratios are derived for an FM (frequency modulated) system in which the r-f (radio-frequency) carrier is strong compared with the noise. The results are derived in a simple way without making use of high-order probability density functions. General formulas are derived for determining the signal-to-noise ratio with periodic modulation or with pulse modulation, and numerical results ... View full abstract»

  • Determination and simulation of the equivalent circuits of electrostatic precipitators

    Publication Year: 1961, Page(s):315 - 320

    Corona field in the usual electrostatic precipitator is energized by half- or full-wave rectifiers operating at line frequencies, the rectifier output being filtered by the capacitance of the precipitator itself. Analysis of the equivalent circuits involved is somewhat complicated. The rectifier, by nature nonlinear, must be considered as well as the nonlinear electrical characteristic of the coro...

    IT IS perhaps not surprising that the fundamentally important advances in the electrostatic method of separating suspended particles from gases have resulted primarily from improved methods of supplying high-voltage power. Both theory and experience bear out the great importance of the methods and apparatus used to supply electric power for the corona discharge in the precipitator, which in turn p...

  • Potentials in D-C corona fields

    A probe method has been devised for measuring potentials in d-c corona fields which are uniform for a short distance in one direction. In unipolar corona, a probe supported by perfect insulators assumes a potential sufficiently above the space so that no more ions can reach the probe. For a cylindrical probe with its axis along an equipotential, this excess or ¿error potential¿ is proportional t... View full abstract»
