In a school experiment, we had to measure an output voltage from an IC. We gathered the data with respect to time. Now we have to find the transfer function given the output data.
I think the whole experiment was treated as a first order open loop system. Now we have to find the transfer function that drove this step response output.
I searched around to find a few equations but still finding that this is a bit hard and requires estimation? Any hints onto how I can do this?
