Fourier Analysis: Drawing Llamas with Circles

https://adekau.github.io/_images/line.gif
The Fourier transform is a method of transforming an input signal from the time domain to the frequency domain. It has a huge range of applications, for instance audio engineers can pick out individual undesired frequencies in a song with the Fourier transform and then get back the sound without that frequency using the inverse Fourier transform. We can make use of the Fourier transform in ...
