Abstract :
An RF pulse signal has been used to investigate the velocity of a wave propagating in a waveguide. Contrary to a recent report, the measurements demonstrate that an RF pulse signal cannot travel faster than light. The energy of the signal is transported at the subluminal group speed that can be measured.<>
