Re: z transform

Hi Onyx;

I have a form for it involving the unit step function.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: z transform

I have a table, hand copied that has it. Also Mathematica does it.

Where theta in this case is the unit step function.

Re: z transform

Mathematica says your welcome. I did nothing but maybe next time.
