File:FFT of Cosine Summation Function.svg

Your FFT diagram seems confusing and incomplete. The DFT, or FFT, is a relation between N input points and N output points, but you've shown the input as continuous instead of discrete. And you don't have the full output, which would show each frequency twice. And you've constructed it to have a real output, which needs at least a comment to explain why it's not complex. Can we work on it? Got code? Dicklyon (talk) 04:54, 19 August 2024 (UTC)
