The Bullard Laws of Harmonics

"To know harmonics is to know the mind of God."

You'll have to read the book to understand them, however, links to online articles are provided to get you started.

1. Harmonic amplitudes are proportional to the area of the distortion.

2. The Harmonic Signature is the result of the angle where the sinusoid impacts the distortion as predicted by the Bullard Harmonic Solution. Harmonics do not just fall off as the frequency increases as is commonly believed.

3. Even harmonics don't appear in symmetrical distortion because they cancel each other out.

4. When a portion of a sinusoid is removed (such as in clipping), the Harmonic Signature mirrors the harmonic signature of the feature removed from the sinusoid.

5. The harmonics of a distorted sine wave will always start at 0, 90, 180 or 270 degrees relative to the fundamental, no exceptions.

6. The harmonic signature will be identical for distortions that happen at the reciprocal angle in the wave
