Using the keyhole contour to “change” the pole you’re evaluating around is actually a really good idea. Amazing technique, I’m learning so much from you, Professor Balakrishnan 😭🙏🏽🎊

It's a very standard approach, you can find that on Gamelin. You're finding it new because you ain't read the book at first place.

But this would mean the residues of these two poles at the 0 and 1 are equal in magnitude isn't it??

Question: he defined an arbitrary generating function using polynomials like z^n. Are we permitted to go with another basis of our choice? It looks like a data-fitting problem to me. Thanks for any answers.
@GHOSTrex13244 жыл бұрын
That was Taylor series of any arbitrary function. As any analytic function would have one so one can assume that.

How is this related to z transform. I find these two things similar, however, I cannot tell the relationship between these two kind of methods.
@wxchew7 жыл бұрын
the generating function is obtain by z transform, the inverse z transform, that is to get the coefficient of the power series, is done by using the contour integration, which is a much more general technique .
@Vercongent10 жыл бұрын
does this technique work even when the contour crosses itself? because that's what's going to have to happen in order to deform the contour so that it encloses those two singularities at alpha and beta @26:52

Vercongent You can approximate the two opposite lines as much as you want, so that their contribution vanishes.
