I know the transfer function = Laplace{output}/Laplace{input}, while gain = output/input, but why is that matter? The ratio will still be the same (or is it?).(adsbygoogle = window.adsbygoogle || []).push({});

And if there is a distinct different, is the result of the mason's formula using signal-flow graph a gain or a transfer function? Wiki says it is a gain but my teacher did an example on the board and got a transfer function at the end.

Thank you so much!
