Minimum phase filter condition
For all causal and stable systems that have the same magnitude response, the minimum phase system has the minimum group delay. The following proof illustrates this idea of minimum group delay. Suppose we consider one zero of the transfer function . Let's place this zero inside the unit circle () and see how the group delay is affected.
