Dynamic tension in the transmission line and its Fourier spectra under two initial energy conditions.
(a) Dynamic tension time history of the transmission line when its initial energy is relatively low
(b) Dynamic tension time history of the transmission line when its initial energy is relatively high
(c) Fourier spectrum of the dynamic tension in the transmission line when its initial energy is relatively low
(d) Fourier spectrum of the dynamic tension in the transmission line when its initial energy is relatively high
