1) But Why (transmission line) Models? The parameters of a 20m transmission line operating at f 95.5 MHz are L 0.4 G 80 and R -20 2 a) What model should you use for this problem? (lumped element or distributed element) Why? Feel free to use the answers to part c) for justification b) Can you use the Low-loss Approximation for this question? Why or why not? b) Find ?, a, ß, ?, and Zo, make sure you state the definition of these terms c) After traveling 20m down the line by what percentage is the amplitude reduced? By how many degrees is the phase shifted? d) Does this meet Heaviside’s Condition? What does this mean?
