if sequence not absolutely summable in z transform

[wajahat]

Hi all ,i want to know if we can't find the z transform of a sequence or sequence is not absolutely summable in z transform then how do we analyse such sequences.
such sequences do exist.
i know some of them.
Any response in this regard would be helpful

If the z transform of the sequence doesn't exist because of no convergence, I would use discrete-time domain for any analysis. It's also possible and sometimes even more effective.

It would be better for both of us, if you introduce to me such sequence. Then our discussion will be more concrete and not so abstract.

With respect,
