Can any one help in solving the below problem?

there is a transmission line with source & load impedance are as shown in the attached diagram in terms of Zo.
Calculate the reflection coefficient of this line at source end as well as at load end.
Plot the voltage (Vout, V1 & V2) wave forms w.r.t the time.

Notation: Characteristic impedance of the transmission line is Zo.
Assumption: Propagation delay of the transmission line to the far end is T.

thanks for your help.

regards,
Subhash C

start v2=0
end v2 is computed using dc voltage divider equation
inbetween, square wave pulses travel back and forth on the transmission line, with diminishing amplitude on each bounce.

The reflection coef at load is simple to calculate, as is the source. Just be mindful of possible sign change at one of the ends of the line!
