Transfer function of a circuit with a resistor, capacitor, and coil

Click For Summary

Discussion Overview

The discussion revolves around finding the transfer function of a circuit that includes a resistor, capacitor, and inductor, specifically focusing on the relationship between output and input voltages in the Laplace domain.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant seeks assistance in identifying errors in their approach to calculating the transfer function, indicating awareness of discrepancies with an answer sheet.
  • Another participant suggests that while the voltage divider method is acceptable, attention must be paid to the reference point for measuring output voltage, which is not the ground.
  • A participant expresses realization of their mechanical application of a formula without understanding its function, indicating a moment of reflection on their approach.

Areas of Agreement / Disagreement

The discussion appears to have multiple competing views regarding the correct approach to finding the transfer function, and it remains unresolved as participants have not reached a consensus.

Contextual Notes

Participants have not clarified specific assumptions or definitions related to the circuit components or the reference points for voltage measurement, which may affect the analysis.

The voltage divider approach is fine, but pay close attention to where the output voltage is being measured; it's not using the ground (source -ve terminal) as a reference...
 
Oh! I used this formula so mechanically already that I forgot what it does and how it functions! Huh... there you go :-)
