The Massie Wireless Telegraph System

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.

An Inverse Problem for the Telegraph Equation

This paper deals with the problem of state estimation for a hyperbolic equation in the presence of unknown, but bounded disturbances, on the basis of information from sensors with finite-dimensional outputs. The object of investigation is the hyperbolic telegraph equation with energy dissipation. Observability properties similar to those introduced earlier for parabolic systems ([8]) are checke...
