Assuming this is a single-input single-output system, you can use all or some of these data sets for transfer function estimation, please see this example in System Identification Toolbox.

Not able to view the example. When I am pressing "this example" the following error is visible. The page you were looking for doesn't exist.

You may have mistyped the address or the page may have moved.
