- Question 1
Repeat Assignment 1 using the example Matlab code for assignment 2, and real data for the input vector x. Choose the real data to be at least one of voice, music, image, and describe the resulting sound or image after passing through a filter. Use the three filters of Assignment 1.

- Question 2
Find the z transform of

- [1 0 0 1] (finite)
- [1 1 1 1 ...] (infinite)
- [1 2 3 4 ...] (infinite)
Hint

Then the signal

**x**is equivalent to:

- [1 1/2 1/3 1/4 ...] or [1 0.5 0.33 0.25 ...] (infinite)
Hint

Using the definition of z-transform, show that

(a)

(b)
