Fourier said that any periodic signal can be represented as sum of harmonics i.e., containing frequencies which are integral multiples of fundamental frequncies. Why did he chose the basis functions i.e., the functions which are added to make the original signal to be sinusoidal? I know sinusoids are orthogonal functions but could we use some other basis functions for this representation?(adsbygoogle = window.adsbygoogle || []).push({});
