Decompose a periodic waveform into its harmonic components — coefficients a0, an and bn, amplitudes and phases.
| n | Frequency (rad/s) | an | bn | Amplitude An | Phase φn (deg) |
|---|
Square, triangle, sawtooth, half-wave and full-wave rectified signals built in.
Every coefficient with amplitude and phase angle, ready for filter or audio design.
Odd/even symmetry instantly tells you which coefficients should vanish.
See the truncated Fourier formula built from your harmonic limit.
