Triangle wave
A wave form in the shape of a triangle which contains only odd harmonics.
the harmonics above the
fundamental
don’t have as much energy as those of a
pulse wave
.

The amplitude of a specific harmonic (relative to the amplitude of the fundamental) is square of the inverse of its harmonic number:
1/n**2
where n is the partial number. Thus the fifth harmonic has 1/25th the amplitude of the fundamental.
