Inadequacies of Sommerfeld's Front Velocity Definition

Authors: Steffen Kühn

Current practice defined the front velocity of a signal as the limit of the phase velocity for infinitely high frequency. However, the present article provides evidence that the propagation velocities of signal fronts for input signals of nonzero temporal duration result from the phase velocities in the low-frequency range. In conclusion, although the impulse response propagates at the so-called front velocity, this is shown not to be true for the step response, and this aspect is shown not to represent a contradiction.
