27. Based on the standing wave you plotted in the graph of Figure 3-22 for ZL = 0, calculate the VSWR at this impedance. To do so, use the loop voltage measured at 3 /4 from the receiving end and the node voltage measured at the sending end. Note: The voltage at the loops and nodes of the standing wave decreases over distance from the sending end, due to attenuation through lossy TRANSMISSION LINEs A and B. Consequently, the VSWR varies over distance, depending on the loop and adjacent node used for its calculation. The loop and node used here have been chosen arbitrarily, just for the sake of showing how the VSWR is calculated. VSWR (0) = According to your result, the VSWR for ZL = 0 is a. not equal to the theoretical value of 1 because the line is lossy. b. much lower than the theoretical value of because the line is lossy. c. nearly . d. lower than the theoretical value of 1 for a lossless line
