ZTransform

Updated In 7 Graphic
ZTransform[expr, n, z]
gives the Z transform of expr.
ZTransform[expr, {n1, n2, ...}, {z1, z2, ...}]
gives the multidimensional Z transform of expr.
  • The Z transform for a discrete function f(n) is given by ∑_(n=0)^(∞)f(n)z^(-n).
  • The multidimensional Z transform is given by ∑_(n_1=0)^∞∑_(n_2=0)^∞… f(n_1,n_2,…) z^(-n_1) z^(-n_2) ….
  • The following options can be given:
Assumptions$Assumptionsassumptions to make about parameters
GenerateConditionsFalsewhether to generate answers that involve conditions on parameters
MethodAutomaticmethod to use
VerifyConvergenceTruewhether to verify convergence
