Compare Equivalent- π and Nominal-π in transmission lines. What are their diffirences? When we use them, in order to do what ?Thank you
If a lossless line is terminated in an inductive load,
(a) will the input impedance be purely inductive, purely capacitive, purely
resistive, or complex when you are 1/2 away from the load?
(b) will the input impedance be purely inductive, purely capacitive, purely
resistive, or complex when you are 32/4 away from the load?
What is a transmission line? When should transmission-line effects be considered, and when
may they be ignored?
