• a technique that exposes the strengths of the sinusoid frequencies and the exponentials that make up a pattern
• indeed it is just the Fourier transform multiplied by an exponential term
• the output imaginary term gives us the coefficient or angular frequency of the sinusoidal
• the output real term gives us the coefficient of the exponential term
• it is also used to turn calculus into algebra:
