Continuous Fourier Transform
Extends Fourier series to non-periodic functions by letting the period go to infinity: X(f) = ∫ x(t) e^{-i2πft} dt maps a time-domain signal to a complex-valued density over all frequencies, with magnitude giving amplitude and argument giving phase at each frequency.
This Concept is waiting for its first lesson!
