The Guarini Repeating Wireless Telegraph System

internal noise in repeating system

the types of transmission systems which today are available for long distance transmission of large numbers of telephone circuits are those for coaxial cables and radio links. the number of circuits is increased in both cases in step with development in technique. radio links have for several years been able to transmit 600 telephone circuits per system. and are now being designed for 960 circu...

Random telegraph signal in a metallic double-dot system.

In this work, we investigate the dynamics of a single electron surface trap, embedded in a self-assembly metallic double-dot system. The charging and discharging of the trap by a single electron is manifested as a random telegraph signal of the current through the double-dot device. We find that we can control the duration time that an electron resides in the trap through the current that flows...

A Bell Telegraph

We show a device with which, apparently, information (in the form of a ”slash-dot” code) is instantly transmitted via Bell state collapse, over arbitrary distance. We discuss some problems and paradoxes arising when this conclusion is viewed in the relativistic framework.

The variational iteration method for solving Nagumo telegraph equation

Active signal restoration for the telegraph equation

We compensate by a prefilter the distortion of an input signal along an electric line modeled by the telegraph equation. The prefilter is based on the so-called flatnessproperty of the telegraph equation. We derive the explicit equation of the filter and illustrate the relevance of our approach by a few simulations.
