Harmonic Content Explorer

How to Use

• Click the Square, Sawtooth, or Triangle preset buttons to load standard waveforms
• Adjust individual harmonic amplitude sliders to build a custom waveform
• Observe the time-domain output and the frequency spectrum simultaneously

What to Observe

• Square wave: only odd harmonics (1st, 3rd, 5th...) with amplitudes 1/n
• Sawtooth wave: all harmonics present with amplitudes 1/n
• Triangle wave: only odd harmonics with amplitudes 1/n² — converges faster
• Adding more harmonics sharpens corners and improves waveform accuracy
