Line conditions on shorted and open lines. The standing wave ratio on a lossless transmission line is measured and found to be infinite.
(a) Can you tell from this measurement if the load is a short or an open circuit? Explain.
(b) Suppose you can measure the line impedance directly and you find that at one point, the line impedance is zero. Moving toward the load a very short distance, you find that the line impedance is purely reactive and increases. Can you now tell if the line is shorted or open? If so, how?
