Two voltage waves having equal frequencies propagate in opposite directions on a lossless transmission line. The lit d f th f d i h lf f th t f th amplitude of the forward wave is half of that of the backward wave. Please determine the total voltage as a function of time and position. ©AGK 2006 ECSE 352 1.5-2 Example Quiz 3 A two wire telephone cable consists of two copper 3. A two-wire telephone cable consists of two copper conductors of radius a =0.5 mm, with a centre-to-centre separation of 2 mm separated by a dielectric of relative permittivity μ r =2.55. The conductors have a conductivity of 5.8 x 10 7 S/m and the dielectric conductivity can be neglected. The cable is operated at a frequency of 1 MHz. ©AGK 2006 ECSE 352 1.5-3
