WebMay 18, 2024 · Yes, it is up to you to divide by N; the factor of 2 depends on how you want to treat the double-sided result which is returned wherein half the power is in the negative frequency, the other half in the positive (and, of course, there's the fact that there's only one DC bin and one Fmax bin). See if the discussion at the following link might help on why … 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.
