Telegraph Equation

Part of the Applied Mathematical Sciences book series (AMS, volume 55)


We shall discuss the voltage and the current in a long cable consisting of two parallel wires stretched along the λ-axis. Let U(λ,t) and I(λ,t) respectively be the voltage and the current at the point of the cable with coordinate λ at the instant t. Then the following relations hold between the functions U and I:
$$ {U_\lambda } = - L{I_t} - RI, {I_\lambda } = - C{U_t} - GU, $$
where R denotes resistance, L self-inductance, G leak-conductance and C capacitance; these quantities are measured per unit length of the cable.
