Question#1:

Start with

where the Region of Convergence for X(z) is |z| > 3. Perform the inverse z-transform (using any method you choose) to find an expression for x(n). Select the correct answer from the list below.

a) x(n) = (1/5)(-2)n u(n) + (1/5)(3)n u(n)

b) x(n) = -(1/5)(-2)n u(n) + (1/5)(3)n u(n)

c) x(n) = (1/5)(-2)n u(-n-1) - (1/5)(3)n u(-n-1)

d) x(n) = -(1/5)(-2)n u(n) - (1/5)(3)n u(-n-1)

--------------------------------------------------------------------------------

Question#2:

Start with

where the Region of Convergence for X(z) is 2 < |z| < 3. Perform the inverse z-transform (using any method you choose) to find an expression fo x(n). Select the correct answer from the list below.

a) x(n) = (1/5)(-2)n u(n) + (1/5)(3)n u(n)

b) x(n) = -(1/5)(-2)n u(n) + (1/5)(3)n u(n)

c) x(n) = (1/5)(-2)n u(-n-1) - (1/5)(3)n u(-n-1)

d) x(n) = -(1/5)(-2)n u(n) - (1/5)(3)n u(-n-1)

-------------------------------------------------------------------------------

Question #3:

Start with

where the Region of Convergence for X(z) is |z| < 2. Perform the inverse z-transform (using any method you choose) to find an expression for x(n). Select the correct answer from the list below.

a) x(n) = (1/5)(-2)n u(n) + (1/5)(3)n u(n)

b) x(n) = -(1/5)(-2)n u(n) + (1/5)(3)n u(n)

c) x(n) = (1/5)(-2)n u(-n-1) - (1/5)(3)n u(-n-1)

d) x(n) = -(1/5)(-2)n u(n) - (1/5)(3)n u(-n-1)
