Transfer function question

  • #1
I had a little query on transfer functions. My problem is this. I have a two port network with one terminal labeled Vin and one labeled Vout. Now network only has 3 components, one is a resistor in series with an inductor, now this series combination is in parallel with another resistor. My question is this, wouldn't the input voltage be the same as the output voltage, making the transfer function just 1? I don't have hardly any experience with transfer functions, teaching myself right now. But it seems to me that since there are basically two branches of the circuit the voltage across the branches should be the same. The first branch encountered after entering the Vin terminal is the inductor/resistor branch, if this makes any difference. Any help is appreciated!

Which of these circuits do you have?

In circuit B, is Vin going into the node between the two resistors?

Can you post a sketch of your exact circuit and label the voltages and ports?
