With the help of Bewley's lattice diagram, show the voltage and current magnitude at receiving and sending end of long transmission line for different time instances. Assume terminating resistance at receiving end as R=(1/2)Zs, where Zs is the surge impedance of the transmission line. The onward travel time for the wave is t. The step voltage source ideal. The unit step voltage is applied at time to = 0 at sending end. Other details, if any, are as per the convention.
