Z Transform: Example Important Solved Problems with formula, steps, derivation and answer based on Z Transform - Second shifting theorem (Time Shifting).

Second shifting theorem [Time Shifting]

1. Z [f(n + 1)] = zF(z) — zf(0)

Proof :

2. Z [f(n + 2)] ‒ z²[F(z) ‒f(0) ‒f(a)z^‒1]

Proof:

3. Z [f(n ‒ k)] = z^‒nF(z)

Proof :

Problems based on Time shifting

(1) 1 / (n + 2)!

(2) cos (n + 1)θ

(3) sin (n ‒ 1)θ
