Response of a System: Transfer Function

AndresPB · Jul 9, 2018

Some time ago I made a modelling project and obtained a plot. Now, I want to remember what the transfer function was, as I want to try changing the parameters.
The graph is the following:

Step response plot, blue curve rising from 0 at about t = 1 s to a peak near 3.6 at t = 2 s, then settling around 3.1 from t = 4 s onward; x-axis Time (second) from 0 to 10, y-axis from 0 to 4, dashed grid.

How can I obtain the transfer function?
Thanks a lot

Was it specific to a biological experiment? Is that why you posted in the Biology forum? If not, I can move your thread to the EE or General Physics forum.

Are you familiar with transforms and using the impulse function to characterize the transfer function of an LTI system? If we knew more about your background, that would help us to help you with this question.
