1000 THE BELL SYSTEM TECHNICAL JOURNAL, SEPTEMBER 1 9 5 2 individual transmission characteristics will produce cumulative errors, making it necessary to maintain close control over the manufacture
HE rapid increase in the demand for long distance or toll telephone service in recent years led to the introduction, about 1920, of carrier systems as a means of securing more intensive use from lo
We study the influence of electrical connection methods on the high speed performance of electro-absorption modulators (EAMs).
A knowledge of the impedance characteristics of loaded lines is of considerable importance in telephone engineering, and particularly in the engineering of telephone repeaters.
T HE transmission of alternating currents over any transmission line between specified terminal impedances depends only on the propagation constant and the characteristic impedance of the line (at
N the early stages of vacuum tube history the theoretical work on d-c. space charge treated mainly potential distributions associated with fairly small initial velocities of the electrons.
All-digital transmitter is a hot topic since a few years.
We show that the benefits of nonlinear compensation techniques, such as DBP, OPC, PCTW subjected to practical non-perfect implementation, are not maintained when the signal bandwidth is increased.
In the present paper we consider the theory of active transmission lines (i.e., lines with gain) with discrete imperfections.
Lined waveguide shows promise as a communication medium. Circular electric wave loss in bends is reduced by a low-loss lining.
