CD Player Exlanation

This will contain my explataion on how a CD player works. Right now I am just trying to figure out the syntax of this program.

The Fourier Series

A Fourier series is an expansion of a periodic function $f$ in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions.

$f(t)=\sum _{k=-\infty }^{\infty }\alpha _{k}e^{\frac {j2\pi kt}{T}}$.
