Triangle wave
A triangle wave is a [waveform] exhibiting periods of increasing and decreasing slopes, switching between positive and negative slopes at peak [amplitude].
The [spectrum] of a triangle wave consists of only odd [harmonic]s in the [harmonic series].
- [amplitude] of the $n$th harmonic = $\frac{1}{n^2}$.
- harmonics 3, 7, 11, etc. are 180 degrees out of [phase]
