Fourier Series Basis
[Periodic Function](https://texonom.com/periodic-function-3fa775a544934003bfbf39101551d1e1) 


### Basic building block is like this
[Amplitude](https://texonom.com/amplitude-abc47e7b6d1c417cabc5b8a17f1d04ed)  $A$, [Frequency](https://texonom.com/frequency-8eb9bc9db08549c98a519d7938c8eb11)  $\omega$, [Variable](https://texonom.com/variable-5461090e225a4cc587a754af46ba4f3e)  $x$, [Phase](https://texonom.com/phase-a46bfc607627430bbeef12e593b51e75)  $\phi$
Add enough of these to get any periodic signal you want even if non-periodic signal
$$Asin(\omega x + \phi)$$
