When the ratio of load voltage to input voltage is 5, the ratio of the characteristic impedance to the input impedance is

Question

Quizplus · Accepted Answer

The ratio of the characteristic impedance to the input impedance in a transmission line is equal to the square root of the load impedance to the input impedance ratio. Since the voltage ratio is given as 5, and assuming the system is lossless, this implies the impedance ratio is also 5. Therefore, the square root is not directly applicable here, and the correct interpretation is that the characteristic impedance to input impedance ratio is directly equal to the voltage ratio, which is 5.
