Question 72easy
A lossless transmission line with Zo = 300 f is excited with a 100 MHz signal. The line is 50 cm long and is terminated in a resistance of 300 f at the load end. If the velocity factor for the line is 2/3, the source impedance for maximum power transfer from source to the line will be
