  Q: A voltage source with internal impedance Z_source = 50 OHm is connected to a transmission line with Z = 50 OHm. Z_load is also 50 OHm. The voltage source generates a single voltage step 1V. What will be the voltage level on the load?
 
 
 
 

 
 
A:
When load impedance Z_load equals Z_transmission_line , the impedance of transmission line matches load impedance. The reflection coefficient= 0. Voltage is divided between Z_source and Z_load.
