Asinusoidalvoltagewavehavingpoweratinputof10Wpropagatesdownalossytransmission line of length 12m, and which has power loss coecient A = 0.05 dB/m. The characteristic impedance is to a good approximation real, and is given as Z0 = 50 ohms. A real load impedance, ZL = 65 ohms, terminates the line.
Evaluate the reflection coecient at the load.
Evaluate the wave power just in front of the load (before reflection).
Evaluate the average power dissipated by the load, and from this, determine the power loss in dB this represents when compared to the line input power.
A portion of the wave will reflect from the load and propagate back down the line to arrive at the input once again. Find the power that returns to the input and express this as a loss in decibels when compared to the original 10W input.
