Talk:Minimum phase

From Wikipedia, the free encyclopedia

In the maximum phase section i think there is an error repeated twice. Instead of "anti-causal and stable" it should be "anti-causal and un-stable" ?

Is the following section correct?

"Minimum phase in the time domain For all causal and stable systems that have the same magnitude response, the minimum phase system has its energy concentrated near the end of the impulse response. i.e., it maximizes the following function which we can think of as the delay of energy in the impulse response."

Even if it is correct it is not clear.
