A 3-Vrms signal is fed to a transmission line whose attenuation at a certain frequency is 0.002 Neper/meter. The length of the line is 3.5 kilometers and it is terminated using an amplifier whose input and output impedances are equal to the characteristic impedance of the line. The amplifier gain is 110 dB. The output of the amplifier is connected to a similar 3.5-kilometer line. The second line is terminated by its characteristic impedance. Determine the signal voltage at the load of the second line.
