(a) Time evolution of a signal at \(f_d= 8.05 \text { THz}\), where the dashed line indicates the the arrival time for a signal with frequency \(f_d\), and (b) FFT of the signal where the precursors have negligible amplitude and the signal onset region is split and symmetric around \(f_d\), similar to the steady state region.
