However, to fully understand how a feedback system behaves, we actually need to look at four different transfer functions. And if our system has a feedforward path, then this expands to six – the so-called gang of six transfer functions. The goal of this video is to provide a little intuition around why we need to look at more than just a single transfer function to fully capture the properties of the system.
