Fourier Transform is very useful if we have a function that is not periodic. As previously discussed Fourier Series is an expansion of a periodic function so therefore we can not use it to transform the function from the time to the frequency domain. Thank goodness for Fourier Transform!

Introduction

Do you want to know how to contact me or find out some interesting things about me? [[1]]

Signals & Systems

Example

Find the first two orthogonormal polynomials on [-1,1]

1. What is orthogonormal? [2]

2. What is orthogonal? [3]

3. What is a polynomial? [4]

        
        

4. Now we can find the values for the unknown variables.



5. Now that we know what the first two orthogonormal polynomials!
