RJM's Demo of Finding Transfer Functions of Dynamic Systems
This page allows the user to see how transfer functions are formed, using the Forward divided by 1-Loop(s) rule.
You can select one of various systems, and then see how Forward, Loop(s) and then the overall Transfer Functions are derived.
These dynamic systems and are modelled using the Laplace operator s, or for sinusoidal signals jω
Click on the relevant blocks in the diagram to change their parameters.
