1) Deduce first principle transmission line equation interms of hyperbolic function. The open wire line has got values of primary constants given  R = 86.26Ω/km, L = 0.252 H/km, C = 0.326 μ farad/km and  G = 0.263 μmhos/km, compute the Secondary constants of transmission line and the phase velocity of line. Operating frequency of the line is 1 Mhz. Deduce characteristic impedance and propagation constants of the dissipation less line. Therefore describe the categorization of the dissipation less line with. Deduce and plot variation of input impedance of lossless line for different terminal impedance.
