## Current Assignment

**Assignment 9**

- Read sections 5.3.3, 6.2, 6.3
- Problems.
- Chapter 5 exercise: 13
- Chapter 6 exercise; 3
- Show that, for a db4 wavelet $\psi_4$, the wavelet coefficients
for a cubic polynomial will be zero.
- Consider the samples of a function f(x) taken at the resolution
2
^{−3} (j = 3) listed below. Suppose that you are
using the db2 scaling function and wavelet.

a^{3} = [2, −2, 0, 4, 5, 1, 2, 3], k = −1 to
6. (I.e., a^{3}_{−1} = 2, etc.)

For each type of padding listed in section 6.3 show the padded signal
required to obtain a^{2}_{k} and b^{2}_{k}
for all possible k using * at least one genuine sample*

Not to be handed in.
