Fourier Transform and frequency components

Fundamentally radio astronomy relies on the Fourier Transform’s ability to extract individual frequency components from measured complex wave functions.

For this introduction, let’s get a conceptual understanding of how a wave can be approximated by the sum of frequencies components. As well as, extracting such components from signals using the Fourier transform.
