Problem-2
A 300 m long line has the following constants: R = 4.5 kÎ©, L = 0.15 mH, G = 60 mmho, C = 12 nF, operated at 6 MHz frequency. Find the propagation constant, characteristic impedance and velocity of propagation.
Solution
Here, the line constant per unit length is obtained as follows.

So, the propagation constant is given as,

The characteristic impedance is given as,

Velocity of propagation is,
