    A new approach to the prediction of electromagnetic compatibility between possible culprit and victim cases is introduced. It is shown that this approach, based on statistical descriptions of case emission and case susceptibility, leads directly to the determination of the probability of interference between randomly oriented equipments in operational situations. Results of tests made using a tech... View full abstract»

    Convenient expressions are derived which permit accurate determination of induced interference in open (unshielded) wire and shielded wire (or coaxial) lines due to ac and transient currents. Curves and tables are presented for obtaining key parameters in the calculation of interference. The limitations of the derived expressions are set forth and an example interference problem is solved. Experim... View full abstract»

  • Shielding Circuits from EMP

    It is generally impractical to filter low-frequency electromagnetic pulse (EMP) signals from victim circuits. Twisting signal pair conductors is helpful but often results in insufficient isolation. The remainder must be provided by shielding. Highly permeable ferritic materials have generally been found to provide maximum shielding from low-frequency magnetic fields. It is shown that this may not ... View full abstract»

  • Method of Assigning the Bandwidth to a Channel

    It is proposed that channel bandwidth assignment be determined by the criterion that a prescribed fraction of the total radiated power of a system be contained within the channel. To apply this criterion to any system, its spectral distribution must be accurately known. Illustrative examples are given for this channel bandwidth computation when the output spectrum is, 1) optical (Lorentzian) shape... View full abstract»

    When substantial harmonic power exists at the input of a radiating antenna, a lobe structure will result that may create a substantial interference problem. In addition, the privacy of the radiating source may be severely hampered. These harmonic fields are generally dependent upon: 1) the order of the harmonic relative to the geometry of the antenna, 2) the impedance the higher harmonic sees at t... View full abstract»

    Assuming that the ac-source impedance has a pure resistance only for the fundamental-frequency component and zero impedance elsewhere, the charging characteristics of a linear detector are analyzed, and the charge time is determined as a function of the circuit constants. Useful information on the design of a linear detector with specified charge and discharge times is given. The American Standard... View full abstract»

  • Investigation of Choke Blinders for Feed Horns of Radar Antennas

    Previous studies with some reflector type antennas have shown that wide-angle radiation and consequently radiofrequency interference (RFI) can be reduced by using choke blinders on the E-plane edges of feed horns. These choke blinders, which are arrays of choke slots or grooves, were designed such that the depth and the separation of the slots were a quarter wavelength. Subsequent efforts have bee...

  • Comparative Radio Noise Levels of Transmission Lines, Automotive Traffic, and RF Stabilized Arc Welders

    Radio interference data that have been measured throughout the frequency range of 30 Hz to 1 GHz on power transmission lines, automotive traffic, and RF stabilized arc welders by many investigators have been assembled, converted to a common system of units, and collectively plotted. The resulting composite presentations permit an assessment of the relative interference levels produced by the three... View full abstract»

    This paper deals with the problem of making frequency assignments to communications equipments in circumstances where spurious responses and intermodulation effects must be taken into account. The concept to be discussed makes use of mutual interference charts (MIC) to select the order of equipment assignment, the frequencies of assignment, and the effects of such decisions on subsequently assigne...

  • Computer Expression for Predicting Shielding Effectiveness for the Low-Frequency Plane Shield Case

    A computer expression for predicting the shielding effectiveness of an infinite plane shield has been developed for low frequencies (below 50 kHz). It is shown that this expression, which arises as a special case of the solution of the general wave equation, is a sum of the attenuation term of Schelkunoff's transmission theory and a remainder, which is in integral but calculable form. The computed... View full abstract»

    A generalized approach to EMC analysis and measurement requirements is given, considering relative parameter importance as well as the inherent uncertainties in input variables, output criteria, and consequent operational decision-making. A sample problem is provided illustrating the results obtained when three different criteria are employed. View full abstract»
