If the -transform of a function is known analytically, the inverse -transform can be computed using the contour integral (2) where is a closed contour surrounding the origin of the complex plane in the domain of analyticity of (Zwillinger 1996, p. 545) The unilateral transform is ...

This famous “z transform” is named for this z. Note that the so-called z transform is not really a transform at all. It is just a collection of techniques that revolve around z and various powers of z, where z−1 is the phasor representation of a delay....

InverseBilateralZTransform[expr, z, n] gives the inverse bilateral Z transform of expr. InverseBilateralZTransform[expr, {z1, ..., zk}, {n1, ..., nk}] gives the multidimensional inverse bilateral Z transform of expr.
Z-transform partial-fraction expansion Syntax [r,p,k] = residuez(b,a) [b,a] = residuez(r,p,k) Description residuez converts a discrete time system, expressed as the ratio of two polynomials, to partial fraction expansion, or residue, form. It also converts the partial fraction expansion...
how to convert z transform transfer function to difference equation?You can use the 'iztrans' function to calculate the Inverse Z transform of the z transform transfer function and further manipulate it to get the difference equation.
