Discussion Overview

The discussion revolves around solving operational amplifier (op-amp) questions, focusing on understanding circuit models, transfer functions, and specific problems related to op-amps. The scope includes homework-related inquiries and conceptual clarifications regarding op-amp configurations and their characteristics.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants express uncertainty about solving op-amp questions and request assistance.
  • One participant mentions having solved the first question but struggles with the second, suggesting it involves a low pass filter model and a transfer function of the form k/(tau*s+1), yet they are unsure how to determine values due to the presence of 's' in the equation.
  • Another participant emphasizes that even self-study questions belong in the homework category and prompts for the transfer functions of both stages of the circuit.
  • There is a request for clarification on the transfer function and the effects of connecting the op-amp in a follower configuration.

Areas of Agreement / Disagreement

Participants generally agree that the discussion pertains to homework-related problems, but there is no consensus on the specific solutions or transfer functions being discussed. Multiple viewpoints and uncertainties remain regarding the approach to solving the questions.

Contextual Notes

Some participants have not provided their attempts at solutions, which may limit the depth of feedback. The discussion includes unresolved questions about transfer functions and the implications of different op-amp configurations.

Welcome to the PF.

We do not do your homework for you. Please show us your try at solving the questions, so that we can offer comments on your work.
 
i solved first question

in second i don't understand something

i think the model is low pass filter and i should find gain=k/(tau*s+1) but i can't find a value because of s in equation.

and it is not my homework.

Thanks again

As long as it is schoolwork (even for self-study), it belongs here.

What transfer function do you get for the first stage? What transfer function do you get for the 2nd stage?
 
sorry i wrote wrong i solved second.
I have a question about the first question.

What is your question? What is that transfer function? It has a basic characteristic. What happens when you connect the opamp in the follower configuration? What is its overall transfer function with that feedback?
