Question

In the theoretical example of an infinite line, the transmitted signal would gradually lose all of its power. consequently, there would be no power reflection toward the generator, as if:________.

a. a perfectly matched load were continually absorbing all the received power.
b. the line were short-ended.
c. the line were open-ended.
d. none of these.

Answer 1

In an infinite line, all the transmitted power is lost through dissipation, as if a perfectly matched load were absorbing it, preventing any reflection back toward the generator.

Step-by-step explanation:

In the theoretical example of an infinite line, the transmitted signal would gradually lose all of its power. Consequently, there would be no power reflection toward the generator, as if a perfectly matched load were continually absorbing all the received power.

The correct answer is a. a perfectly matched load were continually absorbing all the received power. This situation suggests that the transmission line is infinitely long and the signal is entirely dissipated as it propagates along the line, meaning the power is fully absorbed just like when a load perfectly matches the line's impedance.
