WebThe delta functions make the inverse Fourier transform trivial and give the same combination of exponentials and/or sin/cos's. The question is that some of the roots are complex numbers, but k was supposed to be real in the Fourier transform. How should the Fourier (and inverse) transforms be defined in such cases? WebWait! We need to offset each spike with a phase delay (the angle for a "1 second delay" depends on the frequency). Actual recipe for a frequency = a/4 (no offset) + b/4 (1 second offset) + c/4 (2 second offset) + d/4 (3 second offset). We can then loop through every frequency to get the full transform.
