when $Z_L = Z_0 \implies K = 0, Z_{in} = Z_0$
However, in general $Z_L$ can be expressed
as $Z_L = R + iwL$ if the load consists
of inductor an resistor.
Example: If for a distortion less line
has $\alpha = 1.15 \times 10^{-3} m^{-1}$ and $Z_0 = 50 \Omega$,
C = 0.1 nF/m. Find the resistance,
- inductance, conductance per unit lengths
and the velocity of voltage and current
propagation. Find the reflection coefficient for
Solution $Z_0 = \sqrt{\frac{L}{C}} = 50 \Omega, \alpha = R \sqrt{\frac{C}{L}}$
Here $GL = RC$ [No distortion]
