Hi guys
I'm having a little difficulty determining the input impedances for the circuit
I need to determine, when the lines are disconnected
1)Zin looking into line 1 towards the 200Ω load.
2)Zin looking into Line 2 towards the short circuit
With lines RECONNECTED
3) Zin looking into line 3.
For question 1 I have
Zin = Zo[(ZL + jZotanβl)/(Zo + jtanβl)]
and l = λ/4 and β = 2π/λ
βl = π/2
or (Zo^2)/ZL
but I don't know what Zo is???
For question 2 I have.
Zin = Zo[(ZL + jZotan(π/2))/(Zo + jtan(π/2))]
ZL = 0
Zi = Zo[(jZotan(π/2))/Zo]
=jZotan(π/2) = ∞
so it appears as an open circuit
I have no idea how to approach question thee .
would it be λ/2 wave length for both line one and line two?
how on earth do I fined Zo for my calculations???
thanks guys
