What is the condition for properly terminated transmission line?
Proper “termination” of a transmission line consists of connecting a resistance to the end(s) of the line so that the pulse “sees” the exact same amount of impedance at the end as it did while propagating along the line’s length.
What is termination transmission line?
In electronics, electrical termination is the practice of ending a transmission line with a device that matches the characteristic impedance of the line. Termination prevents signals from reflecting off the end of the transmission line.
Why do transmission lines have reflection?
When a wave travels on a transmission line and finds an impedance mismatch, part (or all) of it is reflected back in the opposite direction. If the impedance of the line doesn’t match the impedance of the load, a reflection takes place and some of the power is reflected back.

What kind of current does a transmission line carry?
•Transmission line is a specialized cable designed to carry alternating current of radio frequency, that is, currents with a frequency high enough that its wave nature must be taken into account. Courtesy Wikipedia 9/18/2017 Spring 2016 3
