Homework Two

Something I have learned in class so far...

---

The main thing that I have learned in Signals & Systems is that the Fourier Series $\sum _{n=1}^{\infty }a_{n}\cos {\frac {2n\pi t}{T}}$ can be describe in a vector space, ${\vec {x}}$.

I have also learned that $e^{\frac {j2\pi (n-m)t}{T}}$ is very important because it is the eigenvector to everything that is time-invariant. (I believe I said that correctly.)

Actually it is the eigenvector for every linear time invariant system.
