I'm supposed to realize a plot of SWR of transmission line with a matching load to the normalized frequency. I don't know how to set it up. Any help would be appreciated.

 

What frequency do you want to have the value 1, after you normalize?
What do the instructions say about needing to know the design frequency fo?
Do you know how to compute SWR?

 

There is no need to define a value for f0. I don't know how to compute SWR

 

I like this game...
What is SWR?

 

Standing Wave Ratio. It is the Ratio of the impedance from the load to the Input impedance in a transmission line right?

 

Standing Wave Ratio. It is the Ratio of the impedance from the load to the Input impedance in a transmission line right?

Almost, and only if the load is purely resistive and unequal to the characteristic impedance.
It is actually related to the ratio of reflected power to incident power on a load.

Here is an article on the subject with a method to calculate it.
