Overview
This VI shows how to create and display first order and second order systems

Steps to implement or execute code

  1. Select the initial guesses, upper and lower limits for input values.
  2. Press Run


Block Diagram Steps:

  1. Input initial data, including limits and guesses
  2. Select which type of system you are replicating
  3. Create a Transfer Function
  4. Estimate the Transfer Function
  5. Simulate the model
  6. Draw the model as an equation, calculate L and C values from known R, display simulated response
