Exercise 66

The characteristic impedance of a given lossless transmission line is 75 ( ). Use a Smith chart to find the input impedance at 200 (MHz) of such a line that is: (a) 1 (m) long and open-circuited, and (b) 0.8 (m) long and short-circuited. Then (c) determine the corresponding input admittances for the lines in parts (a) and (b).
