Jul 24, 2012 · Inverse Z-Transform with Examples represents the discrete time fourier transform of (r^-n*x (n)). The Fourier inverse of X (r*e^ (j*ω)) is x (n)* (r^-n) = (1/ (2*π))* ∫ X (r*e^ (j*ω))* e^ (j*ω*n) dω Multiplying by (r^n) on both sides, we get, x (n)= (1/ (2*π))* ∫ X (r*e^ (j*ω))* (r*e^ (j*ω))^n dω Changing the variable of integration from ω to z
