Telegraph equations are presented in a nonstationary form. They were initially obtained for a telegraph communication line, but today they are also used to model the movement of insects, ...

When telegraph technology was developing in the second half of the 19th century, it became apparent that, to describe a message transmitted in Morse code, this equation had to be modified to take ...

Telegraph equations are presented in a nonstationary form. They were initially obtained for a telegraph communication line, but today they are also used to model the movement of insects, ...

The telegraph equations, in particular Heaviside's distortionless circuit, heat flow in one dimension, liquid flow in two dimensions and vibration problems give excellent illustrations of the use ...
