In a transmission line terminated by characteristic impedance, Z0

Detailed Solution for Test: Transmission Lines- 1 - Question 3

When a transmission line is terminated by an impedance Z, then reflection coefficient are:

Here, Z0 = Characteristic impedance of transmission line.
Since Z = Z0 therefore reflection co-efficient of voltage (pv) and current (pI) both will be zero, i.e there will be no reflection of incident wave.
