Introduction

1. In the problem 2.4, we verified the commutative, associative and distributive properties of

convolution for a specific set of signals. And mainly uses the conv() to solve this problem.

2. In the problem 2.5, we mainly use the conv() and filter() functions to solve the problems. We

The two methods gave the same result. So the distributive property is verified.

The results are the same. So the associative property is verified.

As shown below, we can see that when using the commutative property, the outputs are the

same if changing the input and impulse response of the system

. And we can
