Abstract:

Transmission of nanosecond and subnanosecond pulse-coded information between successive processors can be accomplished only if the physical interconnection takes the form of a transmission line terminated in its charac teristic impedance, i.e., if reflectionless, distortion-free transmission between processors occurs. This fact is used as the basis for the investigation of intercoupled transmission lines. Differential matrix equations are developed from Maxwells equations applied to multiconductor systems. The fact that wideband application is desired is used to restrict the general solu tions to expressions which permit the propagation of a single TEM mode only. It is shown that lossy intercoupled transmission line systems can be constructed with the property of distortion free, single-mode propagation generalized Heavi side systems. The specialization of this type of network to two intercoupled lines, which in turn are restricted by unidirectional propaga tion requirements, leads to the double-pair transformer. The suppression of the two re flected waves is possible if the termination impedances are functionally related to each other. These relationships are derived and their physical implications are interpreted to demand that at let one of the termination impedances is an active impedance. Author
