1. The problem statement, all variables and given/known data Incase formatting of numerical answers below is weird, please see attached picture of question. "Consider a distortionless transmission line with impedance 50 Ω, capacitance 0.1 nF/m and attenuation 0.01 dB/m. Find: (a) the resistance, inductance and conductance of the line (b) the wave propagation velocity in the line (c) the relative amplitude of a voltage after it has traveled a distance of 2 km in the line. [Ans. (a) R = 0.057 Ω/m, L = 2.5 x 10 -7 H/m, G = 2.3 x 10 -5 S/m; (b) v = 2 x 10 8 m/s; (c) 10%]." 2. Relevant equations Zo = SQRT(L/C) For distortionless line R/L = G/C 3. The attempt at a solution Part b) is easy (from u = 1/Sqrt(LC)) However, I assume Zo = 50 ohms, as it lets me find L = 502*0.1n = 2.5E-7 But then what the devil do they mean in the numerical answer given for R = 0.057ohm/m? and what is with the conductance G? that isn't 1/any R value. Is that conductance and R wrong? More pressingly though, my log is really rusty! this is where I'm most confused, I've been messing around with e^-attenuationconstant*distance and a loss = 0.01dB = 20 log(V1/V0) formula but I'm not sure if that's the right approach as I'm not getting anywhere? Could anyone offer an opinion and if possible show me how the loss is 10% over 2km? Thanks heaps!
