Enter a fundamental frequency the way it is actually written — 16.384M, 32.768k, 2.4 GHz — and get its harmonics with everything you would otherwise work out separately: the period, the wavelength in either electromagnetic or acoustic terms, and which allocated radio band each harmonic lands in. That last one is the point for anyone chasing interference: a 16.384 MHz crystal putting its sixth harmonic straight into the FM broadcast band is the kind of thing you want flagged rather than discovered. Harmonics in the audible range also get their nearest note and deviation in cents, which makes the harmonic series legible as music. Filter to odd or even harmonics, and copy the table as CSV.

Wavelength in
Symmetrical waveforms — square and triangle waves, and a push-pull amplifier stage — produce only odd harmonics.
