ECE3300 MiniExam #4 Transients on Transmission Lines
Name _______________________________ ECE3300 Student Number ________
You may use your calculator, portfolio, notes, and book. You have 30 minutes.
A 50 ohm transmission line is 10 meters long. The velocity of propagation is 2/3 the
speed of light. The generator has an impedance of 25 ohms, and the load is 200 ohms.
The generator is putting out a pulse that looks like this:
a) Sketch the voltage at the input to the line (z=0 meters) as a function of time for
the first 250 ns.
b) Sketch the voltage on the line (from z=0 to 10 meters) at time = 125 ns.
