Sinusoidal Traveling Waves

The theory of transients arising from the sudden application of a sinusoidal potential is presented in this paper, for the distortionless transmission line. The solution is given in the form of a series of damped sinusoidal traveling waves, the reflections diminishing progressively until the steady state is reached. Oscillographic tests on an artificial line containing lumped parameters are shown to corroborate the theory, and graphical methods are described which permit a quick computation of the successive traveling waves.
