Question: i a lossy transmission line has the following primary constants...

Question details

i)
A lossy transmission line has the following primary constants: R = 55 mΩ/m, G=600 pS/m, L = 600 nH/m and C = 40 pF/m. The transmission line is used to transmit a signal at 1 kHz. Calculate the phase velocity of the 1 kHz signal. Also calculate how much in dB the magnitude of the signal will be attenuated after 10 km.
ii)
Will the attenuation and phase velocity be the same for a 2 kHz signal? What do you call this phenomenon?
