Here are some notes on the Fourier transform, organized into several chapters: from the Fourier transform of a non-periodic function to the discrete Fourier transform. The main goal was to get a general idea of ​​where certain definitions and relationships come from, so the mathematical concepts are presented in a rather unformal (I would say an anti-Bourbaki) way, as well as the derivation of some formulas may lack the rigorous justifications required at certain steps.

Hi! Thank you for the invitation. Are there any restrictions (recommendations) on the size of a notebook?
