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

AI Thread Summary
The discussion revolves around understanding the transfer function of a two-port network comprising a resistor in series with an inductor, which is then in parallel with another resistor. The user questions whether the input voltage (Vin) equals the output voltage (Vout), suggesting a transfer function of 1 due to perceived equal voltage across branches. Participants request a circuit sketch for clarity and to confirm the configuration of the components. The conversation highlights the complexities of analyzing transfer functions in circuits with multiple branches. Understanding the specific connections and components is crucial for accurately determining the transfer function.

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?
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
