I'm pretty familiar with solving z transform, Region of convergence, all I've read throughout my semester while working with digital signal. But intuitively i somehow lack what does z-transform gives geometrically. I know that it's a power series expansion. If x[n] is the sequence, then it's z transform is given as:



$$ X(Z) = sum_n=-infty^infty x[n] z^-n $$



It's just the power series expansion,where:



$$z = r*e^itheta$$



To clarify my question consider the unit step signal.



$$x[n] = 0 for n<0, 1 for n>0 $$



for the above signal Z transform is:



$$X(z) = fraczz-1, ROC: |Z|>1$$



What is the geometrical interpretation for that? Likewise, determinant of 3 by 3 matrix gives the volume.

    There isn't a particularly strong geometric motivation. This is essentially a Fourier transform, though, so if you have intuition there then you might find that it applies here as well.
