You send a nice Gaussian pulse through some medium that gets saturated, so the later part of the pulse is attenuated, and then observe that the peak of the pulse arrives earlier. This is like if I race two lizards that reach the finish line nose-to-nose, but one has had its tail cut off; the "middle" of the shorter lizard reaches the finish line before the "middle" of the longer lizard, but that doesn't mean that maiming a lizard makes it faster. | |
