Exercise 108

In a laboratory experiment conducted on a 50-( ) lossless transmission line terminated in an unknown load impedance, it is found that the standing-wave ratio is 2.0. The successive voltage minima are 25 (cm) apart, and the first minimum occurs at 5 (cm) from the load. Find (a) the load impedance, and (b) the reflection coefficient of the load, (c) Where would the first voltage minimum be located if the load were replaced by a short-circuit
