I have 4 systems which are represented in z domain like this:
Where I know the poles and zeros.
Then I compute Partial Energy Sequence of impulse response of all these system using this formula:
And I get this result:
And I want to observe minimum energy delay property of the minimum phase systems can be specified as:
If I am right, the formula above tells us that minimum phase system has a bigger or equal at least partial energy but, unfortunately, you can see in partial energy sequence plot, the minimum phase system has the smallest partial energy!
Am I interpreting the minimum energy delay formula wrong or what am I missing here?
