Analytical Intuition.
Fourier Transform is the Signal Prism. Splits time-based signals into frequency-based pure tones. Rotating vectors in the complex plane. Uncertainty principle: cannot be narrow in both time and frequency.
CAUTION
Institutional Warning.
We are projecting the signal onto a basis of complex exponentials (circles).
