6.2 Line Terminated by Resistive Load
Notation
Excitation by Constant Voltage Source Semi-infinite Line, No Source Resistance
Example: t, ms t, ms
t = 1 ms
Effect of Source Resistance B.C. (+) Wave
Line Terminated by Resistance
B.C:
Define Voltage Reflection Coefficient, Then, Current Reflection Coefficient
For constant voltage source, Actual Situation in the Steady State One (+) Wave and One (–) Wave
Four equations for the four unknowns
Example:
Solving, we obtain
