Igital Signal Processing and Linear Algebra

This math project is to write something about digital signal processing and Linear Algebra, it should be simple and easy. like music CD and the frequencies or something like that. You should start with definitions then explanations and expamples, try to use simple matrices and example, dont try to make it complicated. I will attach the paper instructions that has to be followed.

This book is an easy reference to start with: Linear Algebra and its Applicationby David C. Lay, 4th Edition. in chapter 4.8

you can use as much as references as you want.

If you have any question please dont hesitate to ask.
