Shape extraction from periodic signal
Webb16 mars 2024 · 0. At first, I thought harmonics come from the signal being periodic. However, we know a sine wave is also periodic but contains a single frequency and no harmonics. A harmonic for me is a component (pure sine-wave) with a frequency f k = k f 0 for some k ∈ Z and a certain frequency f 0 called the fundamental frequency.
