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!
