The "'telegrapher's equations "'( or just "'telegraph equations "') are a pair of linear differential equations which describe the voltage and current on an electrical transmission line with distance and time.

Depending on the parameters of the telegraph equation, the changes of the signal level distribution along the length of the single-dimensional transmission medium may take the shape of the simple wave, wave with decrement, or the diffusion-like pattern of the telegraph equation.
