How you get Fourier transform from Fourier series? Do Fourier series becomes Fourier transform as L --> infinity?(adsbygoogle = window.adsbygoogle || []).push({});

I don't understand where discrete A sub n becomes continuous F(k)dk ( where F(k) is exactly like A sub n in fourier series)?

I also have a general question which is;

How to transform a discrete variable to a continuous variable in order to convert a summation to integral?
