    The open-circuit transfer function ¿(p) of the 2-terminal pair network, defined as the ratio of the output voltage to the input voltage, must be regular in the right-half p plane. Poles of ¿(p) on the imaginary p axis, if any, must be simple with residues having zero real part. These conditions are sufficient to realize ¿(p) to within a constant factor by a symmetrical lattice network. If, in a... View full abstract»

  • Design of low-frequency constant time delay lines

    DELAY lines are used in many applications in both high-frequency and low-frequency fields. In low-frequency applications such lines consist of a cascade connection of inductance-capacitance network sections employing lumped constants. Ideally, the line should have no attenuation; its characteristic impedance should be constant, and the phase shift should be a linear function of frequency. With the... View full abstract»

    ELECTRIC power systems have grown tremendously in the first half of the 20th century. This phenomenal increase includes expansion of each of the following components: 1. Greater number of load service points ¿ transmission and distribution stations, industrial plants, and adjacent system interconnections. 2. Greater number of transmission lines, wider range of transmission voltage, and a trend to... View full abstract»

  • Semifinite terminated electric wave filters

    Specially designed filters to work between a finite resistance at one end and an open circuit or a short circuit at the other end can be made to duplicate exactly the attenuation and phase-shift characteristics of image parameter filters terminated in equal resistances. By doing so a 6-decibel flat gain and considerably higher frequency limit due to parasitic elements can be obtained without added... View full abstract»

    THE purpose of this paper is to present some approximate expressions relating the factors that govern the self-excitation in magnetic amplifiers. Possibilities are shown of a compensation of diversities of rectifier characteristics so as to obtain uniform steady-state performance, simply by readjustments of feedback turns, without changing any other factors of design or operation. Moreover, the ef... View full abstract»

    FOR a good many years designers of power transformers and distribution transformers have had a guide number to use in starting their first design.1, 2 This is expressed by the equation Vt = K¿kva where Vt is the volts per turn to use in starting the first design; K is a constant which may vary between relatively narrow limits; and kva is the kilovolt-ampere rating of the transformer. In practice,... View full abstract»

  • The derivation of vector potential from tables for scalar potential

    Publication Year: 1952, Page(s):169 - 174

    IN ELECTROMAGNETIC theory two quantities, scalar potential V and vector potential A, are commonly used and from them the electric and magnetic fields can be derived. The author recently published tables of Green's Functions1 for the solution of partial differential equations in rectangular co-ordinates. The Green's Functions as given in those tables only include scalar potentials. However, in deal... View full abstract»
