Transfer function for two-port network with series and parallel components

Click For Summary

Discussion Overview

The discussion revolves around the concept of transfer functions in a two-port network that includes a resistor in series with an inductor, which is then in parallel with another resistor. Participants are exploring the implications of this configuration on the relationship between input and output voltages.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether the input voltage (Vin) would equal the output voltage (Vout), suggesting that the transfer function might simply be 1 due to the parallel branches of the circuit.
  • The same participant expresses a lack of experience with transfer functions and seeks clarification on the behavior of voltages across the branches.
  • Another participant asks for clarification on the specific circuit configuration, indicating a need for more information to provide accurate assistance.
  • A request is made for a sketch of the circuit to better understand the voltage relationships and the configuration of the components.

Areas of Agreement / Disagreement

Participants have not reached a consensus, as there are differing interpretations of the circuit's behavior and the implications for the transfer function. The discussion remains unresolved regarding the relationship between Vin and Vout.

Contextual Notes

There is uncertainty regarding the exact configuration of the circuit and how it affects the transfer function. The discussion highlights the need for visual representation to clarify the voltage relationships and component arrangement.

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!

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?
