It means that the conductor would behave as a super- +conductor and dielectric would be made of perfect dielectric medium. In a lossless +transmission line, power sent from a generating point would be equal to power re- +ceived at the load end. There is no power dissipation in the line itself. + + +<br/> + fig: Symbol of tline + + +**NOTE: We have to put one space between Z0=50 and Td=3ns**<br/> + + This can be done in the cir.out file after creating the circuit(s) and converting kiCad +to NgSpice. + +## Single Lossy Transmission Line (SLTL) +An appreciable value of series resistance and shunt conductance make up a lossy +transmission line, which allows different frequencies to transmit at various speeds. +In contrast, on a lossless transmission line, wave propagation rates are constant +across all frequencies. As waves move towards the load end of the lossy transmission +line, distortion is caused by a change in speed. +The symbol for Single Lossy Transmission Lines(SLTL) is shown below- + +<br/> +fig: Symbol of SLTL |
